Abstract

We investigate the performance of a magnesium-oxide-doped periodically poled lithium niobate crystal (MgO:PPLN) in an optical parametric oscillator (OPO) synchronously pumped by 530 nm , 20 ps , 230 MHz pulses with an average power of up to 2 W from a frequency-doubled, gain-switched LD seed and a multistage Yb:fiber amplifier system. The OPO produces 165 mW (signal, 845 nm ) and 107 mW (idler, 1421 nm ) of average power for 1 W of pump power and can be tuned from 800 to 900 nm (signal) and 1.28 to 1.54 μm (idler). Observations of photorefraction and green-induced infrared absorption in different operational regimes of the MgO:PPLN OPO are described and the role of peak intensity and average power are investigated, both with the aim to find the optimal operating regime for pulsed systems.
