We report a pulsed intracavity sum-frequency generator in a diode-pumped, dual-wavelength 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 . At diode pump power and Q-switching rate, a maximum orange () output peak power of 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.
