Amplifier cell in Brewster angle

Due to the amplifier dye cell set up in Brewster angle, the reflections and the parasitic lasing are minimized.

This leads to an overall higher performance of the laser output.

·         Reducing of back reflections

·         Reducing of parasitic lasing

·         Reducing of ASE

·         Higher conversion efficiency
