Abstract

We present an OPCPA system delivering 8.8 fs (3.3 optical cycles) pulses with 1.3 microJ of energy at 143 kHz repetition rate. Pump and seed for the parametric amplification are simultaneously generated by a broadband Ti:sapphire oscillator. The spectral components beyond 1000 nm are separated and amplified in an Yb:YAG thin-disk regenerative amplifier. The pulses are characterized using autocorrelation and SPIDER apparatus. With a pulse peak power of nearly 130 MW, the system is well-suited for future table top strong field experiments.

摘要

我们展示了一个光学参量啁啾脉冲放大（OPCPA）系统，该系统能以143 kHz的重复频率输出能量为1.3微焦、脉宽为8.8飞秒（3.3个光学周期）的脉冲。参量放大的泵浦光和种子光由一个宽带钛宝石振荡器同时产生。超过1000纳米的光谱成分在一个镱钇铝石榴石（Yb:YAG）薄盘再生放大器中被分离并放大。使用自相关仪和光谱相位干涉直接电场重建（SPIDER）装置对脉冲进行表征。该系统脉冲峰值功率近130兆瓦，非常适合未来的桌面强场实验。
