Abstract
The use of broadband laser technology is a novel approach for inhibiting processes related to laser plasma interactions (LPIs). In this study, several preliminary experiments into broadband-laser-driven LPIs are carried out using a newly established hundreds-of-joules broadband second-harmonic-generation laser facility. Through direct comparison with LPI results for a traditional narrowband laser, the actual LPI-suppression effect of the broadband laser is shown. The broadband laser had a clear suppressive effect on both back-stimulated Raman scattering and back-stimulated Brillouin scattering at laser intensities below 1 × 1015 W cm−2. An abnormal hot-electron phenomenon is also investigated, using targets of different thicknesses.
宽带激光技术是抑制激光等离子体相互作用(lpi)过程的一种新方法。在这项研究中，使用新建立的数百焦耳宽带二次谐波产生激光设备进行了宽带激光驱动lpi的几个初步实验。通过与传统窄带激光器的LPI结果的直接比较，展示了宽带激光器抑制LPI的实际效果。在激光强度低于1 × 1015 W cm−2时，宽带激光器对背激拉曼散射和背激布里渊散射均有明显的抑制作用。利用不同厚度的靶材，研究了异常热电子现象。
