The Avia 355-20 manufactured by Coherent Inc. is an all-solid-state Q-switched laser that offers 20 W of 355-nm UV output at 100kHz for micromachining applications. The frequency-tripled vanadate laser operatesat pulse repetition rates of up to 150 kHz and delivers beam quality of M2<1.3. The resonator configuration is packaged in a single sealed module in which the optics are rigidly soldered using proprietary PermAlign technology. The pump diodes are mounted inside the laser head and fiber-coupled into the sealed resonator to enable diode replacement in the field, without optical realignment.
