摘要

普林斯顿等离子体物理实验室(PPPL)开发了一种高功率、短脉冲紫外激光系统(强大的皮秒激光器),作为设计产生短波长的x射线激光器的实验的一部分。随着脉冲压缩和最终KrF放大器的增加,激光输出预计将达到1/3-1/2 TW的水平。激光系统,特别是最后的放大器,将与激光靶实验的一些初始软x射线光谱一起描述。pp激光器的前端提供20-30 GW的输出,可以聚焦到~1016 W/cm2的强度。将描述使用该输出来检验预脉冲对激光-目标相互作用的影响的实验。

High Power, Short Pulse Ultra-Violet Laser for the Development of a New X-Ray Laser
A high power, short pulse ultra-violet laser system (Powerful Picosecond-Laser) has been developed at Princeton Plasma Physics Laboratory (PPPL) as part of experiments designed to generate shorter wavelength X-ray lasers. With the addition of pulse compression and a final KrF amplifier the laser output is expected to have reached 1/3-1/2 TW levels. The laser system, particularly the final amplifier, will be described along with some initial soft X-ray spectra from laser-target experiments, The front-end of the PP-Laser provides an output of 20-30 GW and can be focussed to intensities of ~1016 W/cm2. Experiments using this output to examine the effects of a prepulse on laser-target interaction will be described.
