These highly reflective dielectric spherical mirrors are core focusing and beam-shaping elements in Yb-doped ultrafast laser systems, providing stable normal-incidence reflection while adding controlled curvature without degrading beam quality. They are widely used in beam delivery and relay modules, mode-matching sections, and compact optical heads where the beam must be expanded, refocused, or reimaged into scanners, nonlinear stages, or processing optics.

Mirror can be used in I harmonic of Yb:YAG based 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 Spherical Mirrors are engineered to deliver high reflectivity, minimal absorption, and high LIDT, making them a reliable choice for demanding laser applications. Unlike lenses, concave mirrors do not introduce chromatic aberration, making them highly effective in precision imaging systems, beam shaping, and illumination setups.

Optimized for operation at 1030 nm, these -1250 radius of curvature Concave mirrors ensure efficient beam control with exceptionally low loss and virtually no scattering.
