Our high-energy Nd:YAG laser 50/50 beamsplitters are manufactured using high purity fused silica substrates and ultrahard dielectric coatings. These beamsplitters have been specially designed to withstand high-energy pulses and have a high damage threshold. Designed to be used with Spectra-Physics Quanta-Ray lasers, the front of the beamsplitter is coated with a high power beam splitting coating optimized for 45 deg angle of incidence and S or P polarization. The back surface is coated with a high power AR V coat. Offered in 25.4 mm or 50.8 mm diameters, ultrahard multilayer coatings are optimized for high-energy pulses and high damage thresholds. Meticulous production procedures guarantee they will withstand fluences greater than 10[space]J/cm2 at 1064 nm. |
