Single Pass Third-Harmonic Generation of 310mW of 355nm withan All-Solid-State Laser
-
Abstract
A maximum of 310mW average output power at 355nm has been obtained by extracavity frequency tripling with a BBO crystal in a Q-switched Nd:YVO4 laser with 11.2W of laser diode pump power. The single pass frequency conversion efficiency (infrared-to-ultraviolet) is 14.3%. The power stability of the ultraviolet laser is better than 1% in 30min.
