摘要

为了探索不同脉冲束辐照热-力学效应的相似性关系

同时为实验室开展激光模拟X射线热力学效应研究提供参考

分析了脉冲紫外激光(0.308 m)和X射线辐照Al靶喷射冲量的异同性。首先

对二者辐照热-力学效应机理的异同性进行了比较;其次

理论和实验研究了两种脉冲束辐照Al靶引起的喷射冲量

对较低能注量(小于100 J/cm

)条件下两种脉冲束产生喷射冲量的大小进行了对比。研究结果表明

在低能量密度条件下(小于100 J/cm

)由于没有等离子体屏蔽现象

两种脉冲束辐照靶材产生喷射冲量的机理近似。相同能注量条件下

激光与X射线辐照Al靶产生的喷射冲量具有相同的数量级

。两种脉冲束在一定范围内具有一定的可比性。

Abstract

To investigate the similarity on thermo-mechanical effects induced by different pulsed beams

and also to give a reference for the experimental research of thermal and mechanical effects under X-ray radiation using simulation method of laser irradiation

the similarity and distinction between impulse coupling with an aluminum target by the pulsed ultraviolet laser(0.308 m) and X-ray were analyzed. Firstly

the contrast of the mechanism of thermo-mechanical effects between two pulsed beams was compared. Then

a comparative analysis for the quantity of blow-off impulse induced by two pulsed beams coupling with Al materials was performed in lower energy flux (

100 J/cm

) by means of theory and experimental methods. The results show that the generation mechanisms of blow-off impulse are similar in lower energy flux (

100 J/cm

) for the pulsed ultraviolet laser and X-ray

because there are not a phenomenon of plasma shield. The quantity of impulse by these two pulsed beam irradiation has the same order of magnitude of impulse (

) in same energy flux. Therefore

the two pulsed beam effects are comparable within a certain range.
