Solid-State UV Laser for Drilling and Micromachining

The AVIA 355-7 Q-switched, frequency-tripled, solid-state laser delivers over 7W of average power at 355 nm in a package designed to maximize reliability for a minimum cost of ownership. The highest average power is achieved at repetition rates near 60 kHz, but the laser can be operated at pulse rates as high as 100 kHz, enabling very high throughput micromachining processes. Pulse width is less than 30 ns to minimize peripheral thermal effects in these applications. The AVIA 355-7 also delivers high pulse-to-pulse stability. The AVIA 355-7 also includes several automated stabilization mechanisms to ensure total control of the pulse energy, i.e., power on demand. Coherent Inc., Santa Clara, CA; www.Coherent.com.
