EKSMA Optics offers Galilean type beam expanders with thin UV FS lenses suitable for femtosecond applications. Fixed Ratio Beam Expanders are designed to increase the diameter of a collimated input high power laser beam to a larger collimated output beam. Fixed Ratio Beam Expanders can be adjusted for the input beam divergence angle to obtain collimated, divergent or focused beam at the output. They feature non-rotating divergence adjustment by sliding lens design.

In addition to its exceptional nonlinear optical properties, BBO is a good E-O crystal as well. BBO Pockels cells are suitable for systems with high power and high repetition rate. Please contact our sales team for more details.

Beta-BBO crystal, known as BBO, is one of the best non-linear optical crystals with high effective nonlinear optical coefficient, high damage threshold, wide phase matching range and high deep UV transmittance. BBO is the foremost SHG crystal for Ti:Sapphire lasers. With very good mechanical strength, BBO flakes can be as thin as 5 microns, which is ideal for ultra-short-pulse systems.
