Femtoline Components are designed for femtosecond applications with broadband Ti:Sapphire and Yb:KGW/KYW fundamental and harmonic wavelengths. Femtoline series includes laser optics tailored for applications with high power ultrashort laser pulses - low group delay dispersion (GDD) laser mirrors, thin lenses with AR coatings, group velocity delay (GVD) compensation plates, variable attenuators for high power laser applications. Femtoline Laser & Nonlinear Crystal chapter offers a selection of ultrathin BBO crystals for SHG & THG of Ti:Sapphire lasers, BBO and LBO for SHG of Yb:KGW/KYW frequency conversion, thin AgGaS2 crystals for DFG and Femtokits for efficient third harmonic generation of femtosecond Ti:Sapphire laser.
