| 摘 要： | 主要研究了浸入式固体激光光束在冷却液中传播所产生的波前差。激光在冷却液中传输使得冷却液受热升温,从而使折射率的分布不均匀,最后产生了一个附加的波前差。首先通过数值计算得到该附加波前差的理论值,并通过变换多种激光和冷却液参数得出不同条件下的波前差,然后分析这些参数的变化对于波前差的影响,再结合实验进行对比,最终得出影响光束在冷却液中传输所产生波前差的因素。通过分析这些因素为后续工作提供依据。

| Abstract: | The wave front difference of laser beam transmitting in coolant is studied.Laser beam transmitting in coolant makes the coolant heat up,so the refractive index distribution is not uniform,and finally an additional wave front difference is produced.Firstly,the theoretical value of this additional wave front difference was obtained by numerical calculation,and different values were gotten by changing laser parameters and coolant parameters.Then the influence of these parameters on the wave front difference was analyzed.Comparing with the results of the experiment,the influence factors of wave front difference were obtained finally.This provides a reference for the further work. |
