Abstract

Backward Raman amplification of a short laser pulse in a plasma waveguide is demonstrated. With a guided seed pulse of 0.8-microJ energy and a pump pulse of 345-mJ energy in a 9-mm-long optically preformed plasma waveguide, 910-fold energy amplification is achieved. Heating of the plasma by the long pump pulse is identified to be a key issue for plasma-waveguide-based backward Raman amplifiers.

摘要

在等离子体波导中实现了短激光脉冲的后向拉曼放大。在一个9毫米长的光学预制等离子体波导中，利用能量为0.8微焦的导引种子脉冲和能量为345毫焦的泵浦脉冲，实现了910倍的能量放大。长泵浦脉冲对等离子体的加热被认为是基于等离子体波导的后向拉曼放大器的一个关键问题。
