Synchronously pumped optical parametric oscillation in periodically poled lithium niobate with 1-W average output power

摘要

We report on a rugged all-solid-state laser source of near-IR radiation in the range of 1461-1601 nm based on a high-power Nd:YVO4 laser that is mode locked by a semiconductor saturable Bragg reflector as the pump source of a synchronously pumped optical parametric oscillator with a periodically poled lithium niobate crystal. The system produces 34-ps pulses with a high repetition rate of 235 MHz and an average output power of 1 W. The relatively long pulses lead to wide cavity detuning tolerances.The comparatively narrow spectral bandwidth of <15 GHz is suitable for applications such as pollutant detection.#1999 Optical Society of America OCIS codes: 190.4970, 140.4050, 140.3480.
