介绍了在“神光Ⅰ”和“星光Ⅱ”上分别进行的二倍频、三倍频激光照射金盘靶、腔靶、碳氢有机膜平面靶的实验。通过测量硬X光谱推断超热电子特性,结合受激Raman散射光(SRS)和双等离子体衰变(TPD)产生的3/2ω_0谐波的观测,分析各种靶超热电子产生和抑制的机理,并探讨了抑制超热电子的有效途径。
The experiment of irradiating the gold plate target, cavity target and hydrocarbon planar target with the double frequency and triple frequency laser respectively on “Shenuang Ⅰ” and “Xingguang Ⅱ” was introduced. The superheat electron properties were deduced from the hard X-ray spectra, and the mechanism of the generation and inhibition of superheated electrons in various targets was analyzed by observing the 3 / 2ω_0 harmonics generated by stimulated Raman scattered light (SRS) and double plasma decay (TPD) , And discussed the effective way to suppress the hot electrons.
