Abstract

We report a pulsed intracavity sum-frequency generator in a diode-pumped, dual-wavelength $\mathrm{Nd}:{\mathrm{YVO}}_4$ 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 $1342\mathrm{nm}$. At $4.8\mathrm{W}$ diode pump power and $5\mathrm{kHz}$ Q-switching rate, a maximum orange ($593\mathrm{nm}$) output peak power of $>480\mathrm{W}$ was achieved in this laser system using the Q-switch opening-time offset technique. This power is ~1.7 times higher than that obtained with the system operated in a conventional single-Q-switch mode.
