OPTOMAN’s Broadband IBS-coated Ultrafast Laser Mirrors are designed to provide high reflectivity and low Group Delay Dispersion (GDD) across a wide spectral range, ensuring reliable performance for femtosecond and picosecond laser pulses spanning multiple wavelengths. Unlike standard mirrors optimized for a much narrower spectrum, these mirrors support broadband operation, making them ideal for ultrafast systems that operate across a broad wavelength range or involve tunable sources.

This mirror is optimized for operation at 800 nm center wavelength, and a 45° angle of incidence and ensures consistent reflectivity, low GDD, and high LIDT throughout the bandwidth.

Mirror can be used for Ti:Sapphire laser systems, such as:

  • “Mai Tai®” and “Spitfire” by Spectra-Physics
  • “Astrella” series by Coherent
  • “SolsTiS” series by M Squared Lasers
  • “Chameleon” and “Legend Elite” series by Coherent
  • “TIS” series by HT Laser
  • “Gecco” by Novanta Photonics
  • “Octavius” series by Thorlabs
  • “RedDragon” series by KMLabs
