Abstract

Demonstrate a diode-pumped all-solid Q-switched Nd:YVO4 laser that produced ultraviolet output at 266 nm by using BBO single pass fourth harmonic generation.In the experiment,simple straight cavity is adopted.KTP and BBO crystal are used for the second-harmonic generation and the fourth-harmonic generation differently.Harmonic switch is realized from 1 064 nm to 266 nm.At 10.3 W of incident pump power,we generate the average power of 59 mW,peak power of 370 W at 266 nm with the pulse width of 8 ns.
