Sun, Q. Wang, Z. Liu, X. Zhang, F. Bai, X. Wan, G. Jin, X. Tao, Y. Sun] A high efficiency KTiOAsO4(KTA) intracavity optical parametric oscillator (IOPO) is demonstrated within a diode-side-pumped acousto-optically (AO) Q-switched two-rod Nd:YAG laser. With a 25-mm-long X-cut KTA crystal, efficient parametric conversions to signal (1.54μm) and idler (3.47μm) waves are realized. The highest output power of 15.8W including 12.7W signal and 3.1W idler power is obtained at a repetition rate of 7.5kHz and a pump power of 208W, corresponding to an optical-to-optical conversion efficiency of up to 7.6%. The signal pulse duration is 32ns with a peak power of 53kW. At a repetition rate of 12.5kHz and the pump power of 208W, the highest idler power of 3.4W is obtained with a peak power of 14kW and a pulse duration of 19ns. And the beam quality factors (M 2) of the signal and idler waves are determined to be around 2 and 20, respectively. Springer-Verlag, 2011 Sun W.
