【摘要】 在本文中,我们根据强激光脉冲的重复频率较低,脉宽窄的特点,把介质在一个周期中受辐照的温升分为辐照阶段和辐照后热扩散阶段处理。在充分考虑辐照脉冲的周期性特征后,得出了稳定周期运行的系统中光学元件上的温度分布。更多还原

【Abstract】 Considering the fact that the repeating frequency of the high power laser pulses is quite low and the duration of the pulse is very short,within one period,the temperature variation can be divided into two stages,i.e.irradiation stage and thermal diffusion stage.Making full use of the periodic characteristics of the pulsed laser system,the temperature distributions of the optical components irradiated by the periodic pulses have been obtained.更多还原
