【摘要】 以液体甘油为烧蚀靶材,研究了不同环境温度下超短脉冲激光烧蚀后产生的等离子体的推进特性.实验结果表明:甘油产生的动量和烧蚀压力与环境温度密切相关,其原因是甘油的黏度受温度影响较大.更多还原

【Abstract】 Using the liquid glycerol as the target material,the characteristics of the laser plasma propulsion were investigated under different ambient temperature with ultra-short pulse laser ablation.The experimental results showed that the target momentum and ablation pressure were closely related to the ambient temperature.The reason was that the viscosity of glycerol was affected by temperature obviously.更多还原
