金M带谱时空特性测量

TEMPORAL AND SPACIAL CHARACTERISTICS MEASUREMENT OF GOLD M-BAND EMISSION

给出了金Ｍ带发射的空间尺度和时间尺度。用晶体配软Ｘ光条纹相机测得三倍频激光与金平面靶相互作用金Ｍ带发射的时间尺度：ＥＬ＝４６Ｊ，τ＝５７１ｐｓ时，金Ｍ带发射持续时间（ＦＷＨＭ）～８５０ｐｓ。用狭缝配晶体谱仪测得金Ｍ带发射的空间尺度：λ＝１．０６μｍ，ＥＬ＝１０６Ｊ，τ＝５５０ｐｓ时，金Ｍ带发射的空间尺度（ＦＷＨＭ）为５７μｍ；λ＝０．３５μｍ，ＥＬ＝２５～３８Ｊ，τ＝４８０～５７０ｐｓ时，金Ｍ带发射的空间尺度（ＦＷＨＭ）为２７～３９μｍ。

uration of gold M-band emission was measured to be 850ps, by coupling a crystal spectrometer to an X-ray streak camera, under laser condition of: λ=0.35μm, EL=46J, τ=571ps. While the dimension of gold M-band emission was measured to be 57μm and 27～39μm under laser condition of λ=1.06μm, EL=106J, τ=550ps and λ=0.35μm, EL=25～38J, τ=480～570ps, respectively. 
