PRODUCT DESCRIPTION

PRODUCT INTRODUCTION 

Laser Source DIAMOND J Laser is a new generation of carbon monoxide (CO) lasers from Coherent, promise enhanced processing characteristics in applications ranging from glass, ceramic and film cutting and drilling, through medical and aesthetics fractional skin resurfacing.

 

FEATURES 

Short wavelength

CO lasers output at a wavelength of approximately 5 µm, as opposed to 10.6 µm for CO2 lasers. Since some materials which transmit at the longer wavelength absorb at 5 µm, and vice versa, this leads to advantages in various materials processing applications. For example, there is stronger absorption at 5 µm in certain plastic films, polymers and water, as well as some of the dielectric materials and copper oxides used in printed circuit boards (PCBs). This will therefore enable higher efficiency processing of these materials

Thin cut width 

The other significant advantage of shorter wavelength is that it can be focused to a smaller spot size than a longer wavelength. The CO laser output can be focused to a spot 2 times smaller than that of a CO2 laser. This enables the production of smaller holes and features, and narrower kerf widths when cutting.

Versatile

Coherent offers a range of CO lasers with a wide range of power levels and high quality beams (M² <1.2), which enable a wide variety of applications to be handled.
