Pulsed orange generation optimized in a diode-pumped Nd:YVO4 laser using monolithic dual PPLN electro-optic Q switches

We report a pulsed intracavity sum-frequency generator in a diode-pumped, dual-wavelength Nd:YVO(4) laser whose operation was optimized with two electro-optic Q switches built in a monolithic periodically poled lithium niobate (PPLN) crystal. The dual PPLN Q switches, though integrated, are able to...

Summary:We report a pulsed intracavity sum-frequency generator in a diode-pumped, dual-wavelength Nd:YVO(4) laser whose operation was optimized with two electro-optic Q switches built in a monolithic periodically poled lithium niobate (PPLN) crystal. The dual PPLN Q switches, though integrated, are able to work separately at their respective working wavelengths of 1064 and 1342 nm. At 4.8 W diode pump power and 5 kHz Q-switching rate, a maximum orange (593 nm) output peak power of >480 W was achieved in this laser system using the Q-switch opening-time offset technique. This power is approximately 1.7 times higher than that obtained with the system operated in a conventional single-Q-switch mode.
