The new AVIA LX 355-20 from Coherent is an economical q-switched, diode-pumped solid-state (DPSS) laser offering substantially longer operating lifetime than competitive products at similar power levels. The AVIA LX 355-20 delivers 20W (at 50kHz repetition rate) at 355nm, a diffraction limited (M²<1.3) beam, and an expected lifetime of 20,000 hours.

Applications include cutting flex material, chip and mould form marking, IC package trimming, as well as wafer scribing and cutting. In addition, 3D chip package manufacturing tasks such as via drilling and other processing of glass, ceramics, copper and composites are enabled. A particular advantage of the AVIA LX 355-20 is a shorter pulsewidth that reduces the heat-affected zone and enables higher precision processing of thinner materials. 

The AVIA LX 355-20 features a compact size (140mm x 110mm x 620mm), single-unit construction (combining a laser, controller and pump diodes) and three-point kinematic mounting. The only user requirements are 48 VDC power and cooling water.
