Ultrafast Laser Beamsplitter, P Polarized, 25.4 mm, 680-1080 nm

The 10RQ00UB.4 low GVD 50/50 Beamsplitter for Ultrashort Pulses is specially designed to manage the femtosecond pulse to minimize the pulse dispersion and wavefront distortion of reflected and transmitted light. This beam splitter is for P-Polarized light is coated to provide a 50-50 split at 45° angle of incidence from 680-1060nm. A thin UV grade fused silica substrate, with λ/10 wavefront distortion, is used to reduce pulse dispersion from the substrate material. For the UB.4 coating group velocity dispersion is between +50 fs² and -180fs² over 680-1080 nm for p polarized light at 45° angle of incidence. UB.4 coated beamsplitter can be used to split 50% of the P polarized output beam from Spectra Physics ultrafast amplifiers and oscillators namely Solstice and Spitfire, and Mai Tai. This 25.4 mm diameter beamsplitter is designed to minimize pulse dispersion and maximize bandwidth for beam sampling and autocorrelation measurements of ultrafast laser pulses.
