Diode-pumped Nd:YVO(4)-LBO laser at 544 nm based on intracavity sum frequency generation

摘要

A dual-wavelength continuous-wave (CW) diode-pumped Nd:YVO(4) laser that generates simultaneous laser action at the wavelengths 914 and 1342 nm is demonstrated. A total dual-wavelength output power of 1.79 W was achieved at the incident pump power of 18.2 W. Furthermore, intracavity sum-frequency mixing at 914 and 1342 nm was then realized in a LBO crystal to reach the yellow-green range. We obtained a total CW output power of 212 mW at 544 nm.
