These ultrafast IBS-coated dichroic mirrors are wavelength-separation optics for Yb-based femtosecond and picosecond laser systems, enabling clean harmonic routing while preserving beam quality and pulse duration. They are widely used as harmonic separators in frequency-conversion layouts to reflect the 515 nm second harmonic and transmit the 1030 nm fundamental, allowing independent beam delivery, attenuation, and diagnostics for each wavelength. Their high LIDT, low absorption, and minimal Group Delay Dispersion (GDD) support reliable long-term operation in high-peak-intensity ultrafast beam paths where precise spectral splitting is critical.

Mirror can be used for Yb:YAG based ultrafast laser systems, such as:

  • “PHAROS” and “CARBIDE” by Light Conversion
  • “Monaco” series by Coherent
  • “FemtoBlade™” series by Lumentum
  • “TruMicro” series by TRUMPF
  • “IceFyre® FS” series by Spectra-Physics
  • “Satsuma” and “Tangor” series by Amplitude
  • “FemtoLux” series by EKSPLA
  • “FSL1030X2” by Thorlabs
  • “Jasper X1” by Fluence technology
  • “FS Series” by Photonics Industries

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, while transmitting 1030 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.
