Coherent has launched its Matrix 355 BE laser, which is a frequency-tripled DPSS (diode pumped solid state) laser that delivers a combination of low output noise and low beam divergence. The OEM UV laser incorporates an integral beam expander within the sealed laser head, which results in an output beam diameter (1/e2) of 2.2 mm and a divergence of only 0.5 mrad. This low divergence is an advantage in many OEM applications, especially those having particularly long beam delivery paths or requiring high NA focusing.
The new laser is offered with a choice of 1 or 2W of average power and pulse repetition rates as high as 60kHz. As with other Matrix lasers, the Matrix 355 BE is fully RoHS compliant and backed by an 18 month/10,000 hour warranty. The Matrix 355 BE is optimised to deliver long-lifetime operation for precision applications in materials processing and marking, such as stereolithography (rapid prototyping), LCD/FPD titling, memory repair, thin film ablation, internal glass marking, cold marking of plastics and semiconductors, and semiconductor scribing.
