We present a two-stage noncollinear optical parametric chirped-pulse amplification system that generates 7.9 fs pulses containing 130 mJ of energy at an 805 nm central wavelength and 10 Hz repetition rate. These 16 TW light pulses are compressed to within 5% of their Fourier limit and are carefully characterized by the use of home-built pulse diagnostics. The contrast ratio before the main pulse has been measured as 10(-4), 10(-8), and 10(-11) at t=-3.3 ps, t=-5 ps, and t=-30 ps, respectively. This source allows for experiments in a regime of relativistic light-matter interactions and attosecond science.
我们提出了一种两级非共线光参量啁啾脉冲放大系统，该系统在 805nm 中心波长和 10Hz 重复率下产生 7.9fs 脉冲，包含 130mJ 的能量。这些 16TW 的光脉冲被压缩至其傅里叶极限的 5%以内，并通过自制的脉冲诊断技术进行了仔细的特性分析。在主脉冲之前，对比度比分别在 t=-3.3ps、t=-5ps 和 t=-30ps 时测量为 10(-4)、10(-8)和 10(-11)。该光源可用于相对论光物质相互作用和阿秒科学的实验中。
