在脉冲到脉冲的基础上，从工业Nd：YAG激光器中观察到光束质量（M-2）的波动。这是实现了一个紧凑的多平面成像方法，将二次失真的衍射光栅，使9个平面上的一个单一的CCD阵列同时成像。有了这个系统，我们测量了一系列的光束质量与相关的误差（在M-2的变化）的顺序为0.7%。该系统的应用，光纤光束传输和激光打孔。(C)2004年美国光学学会。
Fluctuations in beam quality (M-2) have been observed on a pulse-to-pulse basis from an industrial Nd:YAG laser. This was achieved with a compact multiplane imaging method incorporating quadratically distorted diffraction gratings, which enabled simultaneous imaging of nine planes on a single CCD array. With this system, we measured across a range of beam qualities with an associated error (in M-2 variation) of the order of 0.7%. Application of the system to fiber-optic beam delivery and laser drilling is demonstrated. (C) 2004 Optical Society of America.
