| Abstract: | We have demonstrated an efficient, high-energy singly resonant pulsed KTP-based intracavity optical parametric oscillator pumped by a quasi-continuous wave (QCW) diode-pumped electro-optical Q-switched Nd:YAG laser. 31.5-mJ energy at 1572-nm wavelength and 50.4-mJ pulse energy at 1064 nm were obtained at 10 Hz simultaneously. The total conversion efficiency with respect to diode pump energy was 14%. |
