Abstract
Tunable blue radiation with a tuning range of 340-460 nm has been gene rated using a beta-BaB2O4 crystal for external frequency doubling of a ns-pulsed Ti:Al2O3 laser. By pumping the Ti:sapphire with 94 mJ/pulse of energy from the second harmonic of a Q-switched Nd:YAG laser, as m uch as 5.4 mJ/pulse st 390 nm with a bandwidth of 0.02 nm was obtained . This represents an infrared to blue conversion efficiency of 36% and a total conversion (from 532 nm to blue) of 5.7%.
