The 10Q20HBS.33S High-energy Nd:YAG Laser 50/50 Beamsplitter is manufactured using high purity fused silica substrates and ultrahard dielectric coatings. This beamsplitter has been tested to withstand high-energy pulses and is the ideal choice to work with Spectra-Physics Quanta-Ray lasers. The front of the beamsplitter is coated with a high power beam splitting coating optimized for a 1064 nm center wavelength, 45 deg angle of incidence and S polarization. The back surface is coated with a high power AR V coat. Offered in 1 inch (25.4 mm) diameter, ultrahard multilayer coatings are optimized for high-energy pulses and high damage thresholds. Meticulous production procedures guarantee they will withstand fluences greater than 10 J/cm2 at 1064 nm.
