摘要
利用软 X射线大面积透射光栅谱仪 ,对超短强激光脉冲辐照下玻璃微毛细管靶的软 X射线发射特性进行了研究。测得了不同的激光能量下、不同长度 (3mm、 6 mm、 9mm)的微毛细管的软 X射线发射谱 ,并观察到随着微毛细管长度的增加 ,X射线发射强度增强。
Experiments on the diagnosis of emission spectrum from glass capillary target irradiated by ultrashort intense laser pulses have been carried out with a high efficiency high resolution transmission grating spectrograph. Emission spectra among 15~25 nm at different laser energies and capillary lengths (3 mm, 6 mm, 9 mm) were measured. X ray emission intensity increases obviously when the capillary length is increased.
