| 摘 要： | 利用“神光Ⅰ”输出的～５００Ｊ、１．０５μｍ，～２００Ｊ、０．５３μｍ激光和“星光Ⅱ”输出的～７０Ｊ、０．３５１μｍ激光，实验研究了激光与金圆盘靶作用产生的等离子体对激光的吸收，获得了激光１０°、４５°入射Ａｕ盘靶吸收的波长关系。实验结果与一维平面等离子体吸收模型计算的结果基本相符。

| Abstract: | The wavelength dependence of absorption of laser has been studied experimentally in the “Sheng Guang” and “Xing Guang” laser facility with the gold disks at a some chosen angle of incidence. The experiments show that inverse bremsstrahlung absorption is the main absorption mechanism and the the absorption increases when laser wavelength decreases. Although the absorption of 0.351 μm laser at 10° angle of incidence is higher than that of the others, the absorption of 0.351 μm laser at 45° angle of incidence is only 75% and scattered light is up to 25%. |
