| 摘 要： | 为了验证近红外激光在水面大气传输时的热晕效应，采用缩比实验方法，克服了大口径和高功率系统复杂、实验成本高等实际问题，以理论分析为基础设计了高效的实验方案，对1000nm左右的激光水面大气传输热晕效应进行了实验研究，取得了重要的外场实验数据。结果表明，在选择合适的功率和发射口径情况下，1000nm左右的高能激光水面传输热晕效应可忽略。这一结果对大口径和高功率激光系统设计是有帮助的。

Scaled experiments on thermal blooming of shortwave infrared laser propagation through water surface |
| |
| Abstract: | To verify the thermal blooming effect while high energy laser propagates through the atmosphere above the water surface, an innovative method of scaled experiment was applied to overcome the difficult of complexity and expensiveness of high energy laser system with big aperture. One effective experimental method of laser propagation through water surface was designed based on theoretical analysis. The wavelength of laser is about 1000nm. The experimental results show that: The thermal blooming could be ignored while choosing suitable laser power and beam diameter. And the results are also helpful for the design of high energy laser system with big aperture. |
