We demonstrate the generation of high-contrast 1054nm short pulses based on a mid-IR optical parametric chirped-pulse amplifier with frequency doubling. Measurement-limited contrast higher than 10(9) is obtained over a large temporal range from approximately 100 ps to 3ps before the peak of the main pulse. With the potential of pulse-energy scalability, the demonstrated scheme incorporating further chirped-pulse amplification in the near-IR range is applicable to petawatt power-level laser systems.
我们展示了一种基于中红外光参量啁啾脉冲放大和倍频的高对比度 1054nm 短脉冲的产生。在主脉冲峰值前约 100ps 至 3ps 的大时间范围内，通过测量得到的对比度超过 10(9)。该方案具有进一步在近红外范围内进行啁啾脉冲放大的潜力，适用于皮瓦级功率水平的激光系统。
