We report the mode locking regime of dye laser pumped by 400 ns laser diode pulses. Three green laser diodes operating at 513 nm are used as the pump source. We obtain subnanosecond pulse trains using periodic 1 ns pulse modulation of the power-supply current through the pump diodes. The addition of a saturable absorber results in both a decrease in the pulse duration to 0.2 ns and a good reproducibility of the output radiation..

电流调制绿色激光二极管泵浦的染料激光器的锁模

我们报告了由400 ns激光二极管脉冲泵浦的染料激光的锁模状态。三个工作在513 nm的绿色激光二极管用作泵浦光源。我们使用通过泵浦二极管的电源电流的周期性1 ns脉冲调制来获得亚纳秒脉冲序列。添加可饱和吸收剂既可以将脉冲持续时间减少到0.2 ns，又可以使输出辐射具有良好的可重复性。
