摘　　要：利用振 放双池受激布里渊散射 (SBS)脉宽可调激光系统抽运非临界相位匹配KTP光学参量振荡器(OPO) ,在脉宽从小于 1ns至 6ns之间变化。小能量抽运的情况下 ,实现了OPO低阈值、较高转换效率运转 ,获得了脉宽可调参量激光 ,并且根据长脉冲抽运光学参量振荡器特点 ,结合实验结果对光学参量振荡器的输出特性进行了分析。The non-critical phase-matching KTP optical parametric oscillator (OPO), pumped by dual-cell stimulated Brillouin scattering (SBS) pulse-width-tunable laser system, has achieved tunable pulse-width and comparatively high transforming efficiency with low-power pumping laser of ranging from less than 1 ns to 6 ns. The output character of this OPO is also analyzed along with experimental results according to characteristics of long-pulse pumped OPO.
