Intracavity UV nanosecond lasers

Photonics Industries has released a UV nanosecond laser (the DSH-355-25) that delivers up to 30W of intracavity harmonic average power at 355nm from a compact, rugged, monolithic laser head.

Photonics Industries’s patented intracavity UV generation is based on non-consumable THG crystals with no crystal indexing required. It allows for a simpler optical resonator for better stability, insensitive to ambient temperature changes. The more efficient harmonic conversions enables lighter weight/smaller form factor laser heads that can be mounted on movable platforms.

The higher power intracavity UV nanosecond lasers are suitable for micromachining applications such as flexible PCB cutting and wafer scribing.
