Laser line polarizing cube beamsplitters provide efficient narrowband polarization for higher power lasers. Each polarizer consists of a pair of precision right-angle prisms carefully cemented together to minimize wavefront distortion. The hypotenuse of one of the prisms is coated with a multilayer dielectric polarizing beamsplitter coating optimized for specific laser lines. The four faces are antireflection coated with a multilayer dielectric coating to minimize surface reflection losses at the laser lines.

An unpolarized beam is split into two orthogonal, linearly polarized components. P-polarized light is transmitted, while s-polarized light is reflected, both with negligible absorption. The extinction ratio is better than 1000:1 for beamsplitter made with BK7 glass, and better than 100:1 for beamsplitter made with UV fused silica. These cubes are recommended for use in pulsed laser systems and for purifying polarization in multimode, high-power lasers.

Laser line polarizing cube beamsplitters are available for ten common laser wavelengths. They are offered in two sizes: 12.7 and 25.4 mm.
