High Efficient Second Harmonic at 416 nm and Fourth Harmonic Generation at 208 nm in Compacted All-Solid-State Ti∶Sapphire Laser
Second harmonic and fourth harmonic are generated from Ti∶sapphire laser pumped by a diode-Q-switched, doubling-frequency YLiF4 (YLF) laser at 527 nm. The nonlinear crystal LiB3O5 (LBO) is used to generate the second harmonic wave in the Ti∶sapphire cavity at Ⅰ-phase match with birefringent filter, and β-BaB2O4 (BBO) crystal is used to generate ultraviolet at 208 nm. Maximum average power of 610 mW at 416 nm, and 64 mW at 208 nm are obtained at 1 kHz repetition rate when the pumping power is 3.8 W. The high conversion efficiency is attributed to the birefringent filter which narrows the linewidth of Ti
