【摘要】 本课题研究激光平面靶吸收与转换规律。主要利用“神光－Ⅰ”装置产生的１．０５３μｍ（能量≈４０－５００Ｊ，脉宽≈０．８－１．０ｎｓ）和０．５３μｍ（能量≈４０－２００Ｊ，脉宽≈０．８－１．０ｎｓ）激光脉冲打Ａｕ盘靶，获得不同辐照强度和不同激光入射角等条件下的实验结果，并给出理论分析、计算和定标关系．更多还原

【Abstract】 Laser pulses produced from the SHENGUANG device with wavelength of 1.053 and0. 53μm,energy of about 40-500J,pulse width of about 0.8-1.0ns have been used todrive a gold disk in different laser intensities and at different incidence angles.A scaling relation of laser absorption efficiency is presented.更多还原
