M-2因子可分解为幅值项和相位项。提出了一种改善激光光束质量的方法。该方法对光束的振幅和相位进行了补偿，从而完全改善了光束的质量。在实验中，设置激光放大器将振幅调制为高斯型，并使用可变形镜补偿相位像差。该方法能很好地补偿激光束；激光器的光束质量因子由1.7提高到1.1。(C) 2013年美国光学学会
The M-2 factor could be decomposed as amplitude term and phase term. A method to improve the beam quality of laser beams is proposed. In our method, the amplitude and phase of a laser beam are both compensated in order to improve the beam quality completely. In experiment, a laser amplifier is set to modulate the amplitude to Gaussian type, and a deformable mirror is used to compensate the phase aberration. The laser beam is well compensated by our method; the beam quality factor of the laser is improved from 1.7 to 1.1. (C) 2013 Optical Society of America
