Abstract

Abstract

An efficient laser -diode(LD) pumped Nd:YAG extracavity frequency conversion all -solid -state quasi -continuous -wave(QCW) ultraviolet laser at 266nm was reported. The laser adopted LBO and BBO as the second and fourth harmonic generation crystals, and was pumped by three LD configurations (high polarization LD， low polarization LD and low polarization LD with a Brewster plate) in the experiment. When the pump power was 25 W and the modulation frequency was 10 kHz， 266 nm UV lasers were obtained with the output power of 0.85， 0.61 and 0.72 W, respectively. A high power UV laser was obtained by using high polarization ratio LD with a single pulse energy of 85 μJ， and a pulse width of 5 ns. The corresponding peak power was as high as 17 kW， and the optical -to -optical conversion effi
