Ultrafast Mirrors for Pulsed Lasers

Thorlabs offers several types of ultrafast mirrors for use with femtosecond and picosecond pulsed lasers. Our Low Group Delay Dispersion (GDD) mirrors are optimized for low dispersion and >99% reflectance when used with Ti:Sapphire, Ytterbium (Yb), Neodymium (Nd), Thulium (Tm), or Holmium (Ho) lasers. The Dual-Band Dielectric Mirror has a specialty coating that maximizes the reflectance of the mirror at both 400 nm and 800 nm. For picosecond Yb lasers, we offer high-power mirrors featuring dielectric coatings with high laser damage threshold values. The chirped mirrors are designed specifically to correct for phase distortions that occur when ultrashort pulses travel through an optical system, correcting dispersion. Mirrors with ultrafast-enhanced silver coating are offered in addition to our protected silver mirrors and unprotected gold plano mirrors.
