WHAT IS THE DIFFERENCE BETWEEN CO2, FIBER AND YAG LASERS?

While there are many different types of lasers, at this time there are really only a few families of lasers that have the efficiency and output power to perform large-scale material processing: CO2, Fiber, and YAG Lasers. CO2 lasers are gas lasers that use carbon dioxide as the lasing medium. Fiber and YAG's are solid-state lasers that use elements like Neodymium (Nd), Erbium (Er) and Ytterbium (Yb) diffused in a crystal of Yttrium-Aluminum-Garnet (YAG) or glass (in the case of Fiber) as the lasing medium.

Coherent uses a range of powerful sealed CO2 lasers that emit far-infrared light at a wavelength of 10.6 microns. This wavelength is highly effective in processing a wide range of materials including wood, paper, plastics, glass, textiles, rubber and metals.

Fiber and YAG emit near 1.06 microns and are well suited for processing metals, especially high reflectivity metals like copper, brass and aluminum. Plastic or organic materials cannot be processed with this wavelength.

WHY A LASER CUTTER GOOD FOR YOU?

Are you looking for a more advanced cutter for dealing with various materials that your available tool were unable to do? Not be worried! Your question is now answered with a laser cutter by which your materials should be cut with highest quality and no damage occurred after the process.
In general, most of materials are now come with different shapes and features; some are so hard while another is soft, thin or fragile. Therefore, the machine in need must suit with the material in use so that the finished material is ensured unchanged in shape and feature. For this requirement, the laser cutter is the best one for your safe and effective processing demands.
Not be so worried about how to use a laser cutter, it takes you a little time and few steps to learn and practice because of its friendly-use software. Furthermore, to deal with multiple shapes of material, the laser cutter has been divided into two groups: CO2 and Fiber laser cutter.
- CO2 laser cutter: Partly used for dealing with such non-metallic materials as paper, wood, glass, acrylic, plastic, and so on.
- Fiber laser cutter: On another hand, are those to work well with metals, anodized or plated metals.
Inspire of the type of material in use, a laser cutter could work well with highest quality and precision, and no harm occurred, of course.
With the laser cutter and various materials, you may apply for such purposes as making protopye for product, cutting it out into finished pieces of use, cut edges, or to make molds for products, etc.

WHAT SOFTWARE DO I NEED TO GET STARTED?

The laser works like a printer, so you can use most Windows-based graphic design software programs (such as CorelDRAW, Adobe products, or AutoCad.)

Design your artwork the way you want it to appear on your sample and send it through our print driver, just as if you were printing a document. If you're looking for a low cost, easy to use graphic sofware program, CorelDRAW is an excellent choice.

WHAT TYPES OF GRAPHICS CAN I ENGRAVE AND CUT?

You can engrave scanned photos, logos, bitmaps, other images, text, AutoCad files. Essentially, if you can print it, you can engrave it.

To cut, you will need a vector based graphic, such as an .eps or Illustrator file. Keep in mind the higher the quality of the graphic you're working with, the better your results.

CAN LASERS ENGRAVE ON METAL?

Yes. While our CO2 laser systems can engrave and cut most non-metallic or coated metal materials, our newest system, the FiberMark, was designed to permanently mark all types of metal.

The FiberMark was designed with a combination of affordability and high quality, and features a 50mm by 1200mm engraving area. The flat bed, flying optics design is revolutionary for a fiber laser system and will mark metals over a large work area in a short amount of time

WHAT IS LASER WELDER? HOW LASER WELDER IS APPLIED FOR INDUSTRIAL NEEDS?

A laser welding machine (Laser Welder) is mechanical device in which two or more pieces of material are joined by together through use of laser technology. It includes Spot/Seam Welding, Automated Scanner Welding, Fiber Laser Welding, etc.


Laser welding is ideal for repairing items with a little bit damage on from which may save much costs for user. Furthermore, the reason why laser welder is prefer than other method when being compared due to its precise processing and the ability of making a close seam on welded items

How laser welder is applied?
The laser welder is currently being applied and taking vital play for a wide range of industries such as Dental Laboratories, Molding, and Jewelry due to its flexibility and diversification in handling materials.


Ideal for Dental Laboratories
Laser welder is considered vital for modern dental laboratories in where the dentists can use it for such dental applications as repairing broken clasp, dental bridge, welding connection, extending margin, repairing porosity, and other multiple jobs.
Laser welder in Molding
In most small and big molding factories nowadays, a laser welder can allow engineers to repair engineering molds, die molds or other mechanical tools and parts. This aimed at applying new-updated technologies into repairing jobs to provide customers with best repaired tools for their demands.


Laser welder in Jewelry industry
The jewelry manufacturers and retailers are now applying the laser welding technology in their production chain to create new jewelries with high quality. This was proved the best method which can be replaced for the use of traditional torch as before.


The laser welder, in the field, was applied to seal holes, re-structure porosity on jewelries made of precious metals like gold, silver, platinum, or to re-size ring, bracelet without removing the stone. Generally, the damages on jewelries shall be well and precisely repaired by a laser welder.

The laser welder, in short, is not only applied in the mentioned markets, but also widely used for many other ones such as precision engineering, electricity, automotive or those relating to re-structuring and repairing process. The use of laser, therefore, has never evaluated unnecessary in case of proper use.

CUTTING METAL WITH PUSLED FIBER LASER CAN SAVE YOUR MONEY?

The laser cutter with Pulsed Fiber Laser can be applied to a wide variety of materials ranging from ferrous and non ferrous metals, but also ceramics, polymers and even carbon composites.

These applications below shows examples of various materials cut with a Pulsed Fiber Laser.

1. Aluminium
The use of aluminum in pure and alloyed form is widely used and small intricate parts can be cut in relatively thick material. (Image 1) The surface finish does not have a significant impact as brushed and anodized parts can be cut equally well. Sections up to 2mm thick can be successfully cut, however the effective cutting speed can be low.

2. Titanium
For engineering applications care would be required to ensure that edge oxidation did not degrade the cut edge quality that the laser cutting may not do well. However, for less technically functional applications such as ornamental jewellery the process is ideal, and can be combined with color marking to produce unique jewelry items.

3. Stainless steel
Stainless steel is a widely used material particularly in the medical industry where there are significant fine and safe cutting requirements. Cutting speeds of >20mm/min can be achieved with good quality in 0.5mm thick 304 grade material using a simple scanner system.
Highly Reflective materials

In fact, highly reflective and conductive materials such as copper, brass, silver and gold are considered extremely difficult materials to cut with laser. The nanosecond pulsed fiber lasers (ns Fiber Lasers) with high power densities, however, are ideally to initially cut these metallic materials.

4. Brass
A material is typically considered to be difficult to cut with Lasers and is often used as a test material to develop parameters for cutting gold. With sufficient peak power in the pulses excellent cut quality can be achieved in relatively thick material up to 1mm with 20W HS and 2mm with 40W HM.

5. Precious Materials
The cutting of precious metals such as silver and gold are increasingly being done using Pulsed Fiber Lasers. The ability to do intricate patterns with very low material wastage is highly attractive to the jewellery sector. As an example a high quality ornately patterned silver disk of 20mm diameter has been cut using a 20W redENERGY HS Laser (Image 6).

The cutting quality of metal is ideally suited to vaporization of ns Fiber Lasers. These examples show a diverse range of metallic materials can be successfully showing the extreme versatility of these Laser sources.

APPLICATIONS JEWELRY LASER MARKER OFFERS THE JEWELRY INDUSTRY?

Laser markers have appeared for a long time in most industries, serving the demand of processing, manufacturing, creating prototypes for kinds of products. Especially, since it penetrated into the jewelry market, laser marker once again shows its functions which help jewelry become more and more various in terms of styles and designs.

Your original products, which are crude and sleek at first, would be more eye-catching, bling and delicate than ever before with patterns, details and images marked sophisticatedly by the laser marker. It is quick and definitely safe because the laser technology which is used to manufacture and process products in jewelry industry is called Fiber laser technology. It is one of the most popular and effective kinds of laser.

Jewelry laser markers have improved dramatically in comparison with other machines. This method does not use inkjet, mechanical tools like drills, knives, etc., so when working, it does not touch the product and does not create scraps, dirt on the surface.

Another strong point of a jewelry laser marker is its compact, simple but eye-catching design that is suitable for both small and large working space. Particularly, it is portable in design which facilitates you in business trips to anywhere you go

Besides, its flexibility is showed in applications of marking on precious metals like gold, platinum, silver, palladium, titan, stainless steel, etc.

LASER SURFACE CLEANING - DID YOU KNOW?

Laser Surface Cleaning is the removal of surface debris and contaminated layers by laser fiber technology without damaging the substrate materials.

These applications typically use high repetition rates and short pulses with high peak powers of a laser marker to create the high quality of cleaning result. While part of the removed material is vaporised, some remains as particulate dust and may be collected in a filtration system. This process is repeated until the required depth and area has been reached.

+ The first, coating removal, is characterised by the removal of a layer on the surface of a substrate (paint, rubber coatings and insulation).
+ The second cleaning process refers to the removal of impurities or contaminants deeply embedded within the surface of a material to clean the surface of original material inside.
Laser surface cleaning is a non-contact/non-abrasive process that can replace the use of chemicals or abrasive cleaning. No chemicals are used and there is no secondary waste produced in this process.

Laser surface cleaning can be used for micro-scale or large-scale cleaning surfaces in different applications. The potential applications range in size from large commercial aircraft to microchips typically cleaning the contact areas of plugs and pads and removal of the insulation layer in cables for the electronics industry; surface cleaning of moulds in the rubber and tyre manufacturing industries; and large area stripping of paints from buildings, bridges, aircraft or ships where the use of chemical solvents is restricted.
