| 摘 要： | 报道了采用高重复频率TEA CO2激光器在不同气压下对冲击摆进行大气模式激光推进耦合系数测试的实验.结果发现,在气压为34.6×103 Pa左右可获得最大的冲量耦合系数.这与在不同气压下采用冲击摆进行固体靶激光推进实验中,在34.6×103 Pa左右存在最大的冲量耦合系数相似.从激光等离子体冲击波的角度对这一现象进行了初步的分析和解释.

| Abstract: | The experiment of coupling coefficients for TEA CO_2 laser propulsion (air mode) was reported at various pressures.It is found that the coupling coefficient reaches the maximum value at the pressure of 34.6 kPa,which was similar with the case of the experiment,in which TEA CO_2 laser pulses were focused on the surface of solid targets at different air pressures.In that experiment,the maximum coupling coefficient was also measured at the air pressure of 34.6 kPa.According to the theory of shockwave and plasma at high temperature,the paper gave a elementary analysis and explanation to this phenomenon. |
