【摘要】 用波长为1.06μm、强度为10¹²～10 ¹⁴W/cm²的激光辐照金属平面靶,在点状聚焦和线状聚焦方式下,离子发射速度及其动量呈现各向异性;通过分析低Z靶和高Z靶在不同能量的激光照射下的离子发射速度V_p和消融质量M,研究离子发射的定标规律.更多还原

【Abstract】 The anisotrop of ion emission was observed when laser irradiation of the aluminum or gold targets at 1.06μm wavelength with laser intensity of 1012 to 1014 W/cm2 and configurations of spot-focused and line-focused. The scaling law of ion velocity and the mass ablation have been studied with the analysis of ion emission, the ani-sotropic angular distributions of ion velocity and momentum.更多还原
