摘要

We describe an effective method for obtaining tunable pulse-duration parametric output with an optical parametric oscillator (OPO) pumped by a tunable pulse-duration laser. The influence of pump pulse duration on a parametric laser is also studied according to the coupled wave equations for three-wave mixing. In the experiments, a noncritical phase-matching KTP OPO, pumped by a dual-cell stimulated Brillouin scattering (SBS) wave with pulse duration ranging from 2 to 6 ns, has achieved tunable pulse duration from an OPO from 1.8 to 4.5 ns. The experimental results agreed quite well with theoretical calculations, and the method was feasible and efficient.
