High energy harmonic beamsplitters are similar to regular dichroic beamsplitters. They were specially designed to separate a primary wavelength and its harmonic wavelength from a laser. Spectral Products provides these harmonic beamsplitters for Nd:YAG and Ti:Sapphire laser systems. The 1st surface with a high energy dichroic coating reflects the target wavelength ≥ 99.5% and transmits other target wavelengths ≥ 90% for longer than the target reflecting wavelength or ≥ 85% for shorter than the target reflecting wavelength. The 2nd surface has a high energy anti-reflection coating for the target transmitting wavelength. If the beam size is small (< 3mm diameter) and the minimal beam deviation is needed, our super thin plate could be a good solution.
