ARO has extensive experience supplying optics for demanding solid state laser applications. From us, you can find polarizers with an optimum combination of high extinction ratio, laser damage resistance, and mechanical durability. Our catalog includes high performance, first surface, thin film polarizers designed to work at Brewster’s angle in laser based applications and systems. Below, you will find ultrafast polarizers optimized for Ti:S ultrafast laser systmes in addition to frequency-doubled, tripled, or quadrupled Nd:YAG and Nd:YVO4 laser based applications and systems. We also offer high energy polarizers for both custom and stock solutions. Please contact our technical sales department to discuss custom optics capabilities.

Solid State PolarizerThese high performance, thin film polarizers are first surface coated to separate orthogonal polarizations with a high extinction ratio; the second surface is uncoated. They are available from stock at most common solid state laser wavelengths. They are designed to work at Brewster’s angle, and should be tilt tuned (±3°) to optimize performance. | |||
