Ultrafast Optics for Pulsed Lasers

Thorlabs offers several types of ultrafast optics 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 Yb lasers, we offer high-power mirrors featuring dielectric coatings with high laser damage threshold values. Mirrors with ultrafast-enhanced silver coating are offered in addition to our protected silver mirrors and unprotected gold plano mirrors. Chirped mirrors and dispersion compensation prism pairs are designed specifically to compensate for the pulse broadening effects that occur in ultrafast laser systems. Low-GDD beamsplitters are available with coatings for broadband operation, Ti:Sapphire and Yb harmonics, or Yb lasers. For second harmonic generation, β-BBO crystals are available.
