Abstract
A Kerr-lens, mode-locked YVO4∕Nd:YVO4 laser coupled with an acousto-optic modulator (AOM) Q-switching near 1064 nm was employed to pump an intracavity KTiOPO4 (KTP) optical parametric oscillator. A subnanosecond signal wave near 1572 nm with low repetition rate was realized. At an AOM repetition rate of 8 kHz, the maximum output power was 165 mW. The highest average pulse energy, the shortest duration, and the highest peak power of a mode-locking signal pulse were estimated to be ~10.3 μJ, ~120 ps, and ~82 kW, respectively.
