大功率红外激光功率密度分布的实时检测

Real-time Measurement of Power Density Distribution of a High Power Infrared Laser

在文献［１，２］所进行研究的基础上，本文从理论上研究了一种实时检测红外大功率激光功率密度的方法，利用这种方法，不但可以在激光设备工作的情况下进行测量，而且可以提高测量质量，使得即使不进行对衍射的补偿运算也能获得较满意的结果。

In this paper, a method for real-time measurement of power density distrirbution of continuous high power infrared lasers on the basis of researches in references [1, 2] is introduceds. Using this method, we can cauyont measurement in a state of working of the laser device and raise measurement precision, gaining satisfactory result in the measurement even without making compensation operation to the diffraction effect.
