【摘要】 利用脉宽约为 5 0ps的类镍 银 13 9nm软X射线激光作为探针 ,探测由脉宽 80ps的驱动激光打C8H8靶产生的等离子体在 1ns后的电子密度分布信息 ,获得了清晰的莫尔条纹图像 .对结果的处理 ,给出了峰值电子密度为 1 1× 10 2 1 cm- 3 ,并对在靶面附近莫尔条纹的消失现象作了初步解释更多还原

【Abstract】 A soft X\|ray laser deflectometer was used to measure electron density distribution of a laser\|plasma produced with a 80ps duration drive laser pulse ( λ =1 053μm) irradiating a C 8H 8 plasma target. Using a soft X ray laser beam ( λ =13 9nm) of 50ps pulse duration, a moiré deflectogram was created about 1ns after the end of drive laser pulse. Analysis of moiré deflectogram gave a peak density of 1 1×10 21 cm -3 . A preliminary explanation was made on the disappearance of the moiré stripes near the target surface.更多还原
