| 摘 要： | 介绍了激光加热Cu靶和NaF靶发射的在1.2keV区X射线转换效率的测量方法和实验结果。结果表明,在激光辐照功率密度为1×1013—1×1014W·cm-2条件下,激光波长为1.06μm或0.53μm时,Cu等离子体发射的1.2KeV区X射线的转换率为NaF等离子体的4—5倍;对此两种等离子体,激光波长为0.53μm的X射线转换效率是波长为1.06μm的2倍左右。

| Abstract: | This paper presents the measurement methods and the experimental results of X-ray conversion efficiency in 1. 2 keV region from Cu and NaF plasma produced by 1.06 and 0.53μm laser. These results showed that X ray conversion efficiency in Cu plasma is 4-5 times as high as that in NaF plasma with the laser intensity in 1×1013—1×1014W·cm-2 and wavelength of 1. 06 and 0. 53μm. The X-ray conversion efficiencies in Cu and NaF plasma produced by 0. 53μm laser are about 2 times as high as that by 1.06μm laser. |
