Coherent, Inc. recently unveiled two new low-power CO2 lasers that feature excellent beam quality and a very small footprint. Called the Diamond(TM) C-55 and Diamond C-70, these OEM lasers provide more than 55W and 70W of output power, respectively, at 10.55 to 10.63 µm. The lasers' M2 <1.2 (<1.3 for C-70) beam quality makes them ideal for medium- to high-volume marking, engraving and desktop manufacturing. The C-55 was built using the same laser cavity as its predecessor, the GEM-50. However, it features an innovative platform where the power supply RF driver is integrated into the same housing as the laser head. This results in a compact, robust package that can withstand the most demanding environments.
