OPTOMAN’s Ultrafast IBS-coated Dichroic Mirrors are designed to provide precise wavelength separation, while maintaining high LIDT and minimal Group Delay Dispersion (GDD) for preserving pulse duration and handling high peak intensity of femtosecond and picosecond laser systems.

This harmonic separator is optimized for reflecting 515 nm at a 45° angle of incidence, and transmitting 1000 - 1090 nm, providing precise wavelength separation for ultrashort laser pulses. With reflectance for II harmonic and transmittance for I harmonic, this filter is optimized for Yb:YAG based ultrafast laser systems.
