incident laser energy

In the domain of laser-matter interaction, energy coupling coefficient is defined as the ratio of absorbed laser energy to incident laser energy.

在激光与物质相互作用研究领域中，能量耦合系数定义为材料吸收的激光能量与入射总激光能量之比值，它是表征激光辐照效应的主要参数。

Energy law of similitude for laser propulsion refers to the law that there is an optimum nozzle configuration for the largest value of impulse coupling coefficient at certain incident laser energy.

激光推进的能量相似律，指确定的激光能量有与之相对应的最佳喷管尺寸，使得冲量耦合系数最大且不变的规律。
