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 wavelength separator is optimized for reflecting Yb:YAG I harmonic 1030 nm at a 45° angle of incidence, and transmitting 940 nm, providing precise wavelength separation for ultrashort laser pulses.
