Paper Abstract

A doubly resonant optical parametric oscillator (OPO) was developed with a simple pumping configuration based on our optimized mode-to-pump design. The type II KTA OPO is placed in the cavity of a Q-switched diode-pumped Nd:YLF laser. The linearly polarized Nd:YLF laser at the wavelength of 1053nm generates 6.5 Watts and 11.9 Watts arrange power in TEM00 mode at the repetition rate of 1 and 3 KHz, respectively. We obtain the OPO average power of over 2 Watts with broadband tuning range from 1.7μm to 2.1μm at the repetition rate of 1 to 2KHz. The pulse width is less than 20ns. The maximum OPO energy of 2.5mJ per pulse is obtained at the wavelength of 1.9μm, where the pump energy is 6mJ per pulse and the pump-to-signal efficiency is 42%.
