Second-harmonic generation from regeneratively amplified femtosecond laser pulses in BBO and LBO crystals bbo crystal second harmonic generation The spectral and temporal characteristics and optical-conversion efficiency of ∼150−fs∼150-fs laser pulses at 400 nm generated by second-harmonic generation (SHG) of a regeneratively amplified mode-locked Ti:sapphire laser were investigated both theoretically and experimentally. The theoretical investigation was […]
