Abstract

Abstract We report on the development of an ultrafast optical parametric amplifier front-end for the Petawatt High Energy Laser for heavy Ion eXperiments (PHELIX) and the Petawatt ENergy-Efficient Laser for Optical Plasma Experiments (PEnELOPE) facilities. This front-end delivers broadband and stable amplification up to 1 mJ per pulse while maintaining a high beam quality. Its implementation at PHELIX allowed one to bypass the front-end amplifier, which is known to be a source of pre-pulses. With the bypass, an amplified spontaneous emission contrast of $4.9\times {10}^{-13}$ and a pre-pulse contrast of $6.2\times {10}^{-11}$ could be realized. Due to its high stability, high beam quality and its versatile pump amplifier, the system offers an alternative for high-gain regenerative amplifiers in the front-end of various laser systems.

毫焦耳超快光学参量放大器作为高增益再生放大器的替代品

摘要本文报道了用于重离子实验用Petawatt高能激光器(PHELIX)和光等离子体实验用Petawatt节能激光器(PEnELOPE)设备的超快光参量放大器前端的研制。该前端提供宽带和稳定的放大高达每脉冲1兆焦耳，同时保持高光束质量。它的实现在philix允许一个绕过前端放大器，这是已知的预脉冲的来源。通过旁路，可以实现4.9\倍{10}^{-13}$的放大自发发射对比度和6.2\倍{10}^{-11}$的预脉冲对比度。由于其高稳定性、高光束质量和多用途泵浦放大器，该系统为各种激光系统前端的高增益再生放大器提供了一种替代方案。
