✦ Synopsis
We report an electro-optical Q-switch ultraviolet laser at 355 nm with narrow width and low repetition rate generated by pulsed-diode side-pumped Nd:YAG/KTP/LBO. The single-pulse energy is measured to be 18.7 mJ with a pulse-width of 7.32 ns at a repetition rate of 1 Hz and a pump current of 120 A. We can obtain the output laser of 1064 nm, 532 nm, and 355 nm simultaneously by using a volume of beam splitting mirrors, and the average output power of the three lasers are measured to be 589.8 mW, 305.6 mW, and 218.2 mW, respectively, corresponding to a conversion efficiency of 12.69% from 1064 nm to 355 nm. 355 nm ultraviolet laser spot photo
