These wide-angle dielectric mirrors designed for frequency-doubled Yb-based laser systems preserve pulse fidelity while maintaining consistently high reflectivity across a broad range of angles of incidence, enabling flexible steering of green femtosecond and picosecond pulses without compromising beam quality. They are widely used in ultrafast II harmonic laser systems and optical layouts where the beam path or incidence angle may vary, and where predictable low dispersion is required across the full operating range. Their low absorption coatings, and stable spectral behavior support long-term operation in high-power green-beam paths where angular tolerance, thermal stability, and repeatable pointing are essential.

Mirror can be used for II harmonic of 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 Wide-Angle IBS-coated Ultrafast Mirrors are designed to deliver high LIDT and low Group Delay Dispersion (GDD) while maintaining pulse fidelity across a broad range of incidence angles. Unlike standard mirrors optimized for a fixed angle, this mirror provides consistently high reflectivity and minimal dispersion over a wide angular interval, making it ideal for flexible integration into femtosecond and picosecond laser systems where beam geometry may vary.

This mirror is optimized for operation at 515 nm and a 0 - 45° interval of angles of incidence, providing high reflectivity and low GDD for ultrashort laser pulses.
