FemtoLine product group includes a selection of nonlinear and laser crystals for femtosecond applications. For second and third harmonic generation of Ti:Sapphire laser we offer thin BBO crystals. You could also take a look at Femtokit – complete solution for third harmonic generation of Ti:Sapphire. For frequency conversion of Yb:KGW/KYW we offer a choice of LBO and BBO crystals. Yb:KGW and Yb:KYW crystals with broad emission bandwidth are used as lasing material to generate ultrashort high power pulses.
