The Lexel 95-SHG gas-ion laser provides continuous-wave deep ultraviolet coherent laser light with up to 250mW output. (For lower power output in a more compact laser, see our 85-SHG model.) The 95-SHG laser is based on the proven Lexel 95 series. The 95-SHG is an intracavity frequency-doubled system equipped with a nonlinear BBO crystal, to produce Second Harmonic Generation (SHG) deep UV coherent laser light. It uses the simplest, most stable three-mirror folded cavity design for frequency doubling. This provides two benefits:
True hands-free laser operation in the ultraviolet.
A high-quality TEM00 beam that's suitable even for highly mode-sensitive applications.

Specifications
The BBO crystal (Beta Barium Borate: BaB2O4) is mounted on either a Manual Micrometer Stage or an optional Crystal Automatic Transition (CAT) Stage. The CAT stage provides true hands-free operation for industrial applications, by eliminating the need for BBO crystal tune-up.
A continuous supply of dry nitrogen is required when the system is operating.
