在“星光Ⅱ”激光装置上，利用８０只分立式探测器研究了约０８ｎｓ，０３５１μｍ激光辐照Ａｕ盘靶的吸收、散射．结果表明，强度约为５×１０１４Ｗ／ｃｍ２的激光以１０°角入射，吸收可达９０％以上；但是，以４５°角入射，吸收仅为７５％左右，散射高达２５％．散射主要来自未被等离子体充分吸收的激光在弯曲临界面上的反射，同时伴随少量受激布里渊散射．吸收的理论计算与实验结果进行了比较，两者符合较好． In the “Star Ⅱ” laser device, 80 discrete detectors were used to study the absorption and scattering of Au disk targets at 08ns and 0351μm laser irradiation. The results show that the laser beam with an intensity of about 5 × 1014 W / cm2 is incident at an angle of 10 ° and absorbs up to 90%. However, when it is incident at a 45 ° angle, the absorption is only about 75% and the scattering reaches 25%. Scattering mainly comes from the reflection of the laser, which is not fully absorbed by the plasma, on the curved critical plane, accompanied by a small amount of stimulated Brillouin scattering. Absorbed theoretical calculations and experimental results were compared, both in good agreement.
