宽带与窄带激光打靶的电子温度
Measurement of electron temperature of plasma irradiated by broadband and narrowband laser Beams
摘要
用X射线连续谱仪(K边多道法)测定了宽频带激光打靶产生的等离子体的电子温度。结果表明, 两种带宽的激光打靶产生的热电子温度很相近(在420～500eV范围内);而宽带打靶产生的超热电子温度要比窄带打靶产生的低些。
Abstract
Measurement’ of electron temperature of laser plasma by means of K-edge filter detectors is reported. The results show that for broadband and narrowband laser irradiation the thermal electron temperature at the range of 420-500eV are quite similar, but the hot electron temperatures from 2.5 to 4.0 keV are different. The hot electron temperature for broadband laser irradiation is lower than that for narrowband lager irradiation.
