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