| 摘 要： | 用经典理论推导了强激光大气传输中由于氮的转动受激Ｒａｎｍａｎ散射所造成的对传输功率的限制方程，并计算了光强的阈值，得到了阈光强与激光波长和脉宽的关系；此外，还研究了二维效应和激光脉冲系列通过大气时声子激发的累加效应。

| Abstract: | In this paper, we have deduced a set of equations to study the power limit due to SRRS of N_2 for high power laser propagation in the atmosphere,and calculated the threshold value of laser intensity.The relation between the threshold value of laser intensity and laser wavelength,and pulse width has been obtained.In addition,we have also studied two dimensional effects and accumulation effects of the phonon excitation when multipulse laser beam propagates through the atmosphere. |
