Coherent Inc. has released a Q-switched frequency-tripled solid-state laser that delivers >7 W of average power at 355 nm. The Avia 355-7 achieves highest average power at repetition rates near 60 kHz, but can be operated at up to 100 kHz. Pulse width is <30 ns. Features include an automated crystal shifter that produces uniform power output over the life of the laser and third-harmonic-generation crystal life of 60,000 h. Several automated stabilization mechanisms ensure control of pulse energy, and the Posilock beam position sensor and feedback loop deliver beam pointing stability of <25 μrad/°C.
