Brewster windows

•  Ideal for Laser Cavities

• p-polarized light transmitted without loss

• ʎ/10 transmitted wavefront distortion

• 10-5 Scratch-Dig

Our Brewster windows are made of UV grade fused silica with laser grade surface quality and parallelism, making them ideal polarizers for use inside a laser cavity.

When oriented at Brewster's angle (55.57°), s-polarized light is partially reflected, p-polarized light is transmitted without loss. When placed inside a laser cavity Brewster windows cause p-polarized light to have higher effective gain, resulting in the laser's final output being strongly p-polarized.
