These zero-order air-spaced half-wave plates are used in frequency-doubled Yb-based laser systems to rotate linear polarization and precisely set the power distribution through polarization-sensitive optics without degrading beam quality. They are commonly placed in green-beam delivery and polarization-control sections before isolators, thin-film polarizers, scanners, or diagnostic optics, where stable retardance and repeatable polarization angle are critical for high-power femtosecond and picosecond beams.

Optimized for II harmonics of high-performance femtosecond lasers at 515 nm, these waveplates outlast alternatives and deliver unmatched reliability in demanding systems, including:

  • “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 SuperHero Power IBS-Coated Hald-Waveplates are built to survive the extremes of ultrafast lasers. They introduce a precise λ/2 phase delay at 515 nm between orthogonal polarization axes, enabling reliable conversion of linearly polarized light into circular polarization or vice versa – a function critical for isolators, modulators, and advanced laser setups.

These waveplates feature air-spaced zero-order design with no glue, eliminating stress, drift, and degradation. Combined with IBS AR coatings (<0.1% reflectance), they deliver high LIDT and long-term stability, ensuring years of maintenance-free operation.
