Abstract

An efficient and compact all-solid-state continuous wave 67-nm red laser is generated by intracavity frequency doubling of a diode pumped Nd∶YVO₄ laser at 1342 nm while suppressing the higher gain transition near 1064 nm. With the incident pump power of 40 W and a frequency doubling crystal lithium triborate, as high as 10.5-W output power at 671 nm is achieved. The optical-to-optical conversion efficiency is 26.3% and the output power stability during 8 h of operation is better than 2.3%. To the best of our knowledge, this is the highest conversion efficiency of watt-level laser at 671 nm generated by intracavity frequency doubling of a diode pumped Nd∶YVO₄ laser at 1342 nm.
