啁啾脉冲的放大技术有可能获得多太瓦皮秒和亚皮秒激光脉冲 ,以便进行超强场与物质相互作用研究。本文给出啁啾脉冲放大的多太瓦“进步 - P”型 Nd∶ YLF/ Nd∶玻璃混合激光装置 ,不久前曾在这台装置上进行了一系列 1 0 1 8～ 1 0 1 9W/ cm2 范围内超强场与固体的相互作用实验。图1所示的激光装置由输出能量为～ 1 J的皮秒激光起动系统及六通“进步”型棒状放大系统组成。它可以分为四个功能部分 :起动激光系统、基本放大通道、压缩器和聚焦系统。
Amplification of chirped pulses makes it possible to obtain multi-terahertz and sub-picosecond laser pulses for super-field-matter interaction studies. In this paper, a multi-terahertz “Progress-P” Nd:YLF / Nd: glass hybrid laser device with chirped pulse amplification is proposed. A series of 1 0 1 8 ~ 1 0 1 9W / cm2 interaction between the super field and solid experiments. The laser device shown in FIG. 1 is composed of a picosecond laser starting system with an output energy of ~ 1 J and a six-step “progressive” rod-shaped amplification system. It can be divided into four functional parts: starting the laser system, the basic amplification channel, compressor and focusing system.
