We present a real-time method to determine the beam propagation ratio M2 of laser beams. The all-optical measurement of modal amplitudes yields M2 parameters conform to the ISO standard method. The experimental technique is simple and fast, which allows to investigate laser beams under conditions inaccessible to other methods.
我们提出了一种用于确定激光束光束传播比M²的实时方法。模态振幅的全光学测量产生符合ISO标准方法的M²参数。该实验技术简单快速,能够在其他方法无法达到的条件下研究激光束。
