The laser beam quality factor M2 is an evaluation standard for the quality control and aided design of the laser system. After analyzing the particle size distribution function and the working principle of laser particle sizer, the effect of laser beam quality factor M2 on the measurement results of Laser Particle Sizer is emphasized. The results show that the M2 factor mainly results from the two aspects of the beam divergence and the waist width of the beam. The simulation example analysis draws the following conclusions: The size of the beam divergence angle is proportional to the error value, that is, the smaller the divergence angle, the smaller the error. In the M2 factor selection range (1 1.8) the influence of the beam waist width on the measurement results of the instrument is negligible. Moreover, the M2 factor is directly proportional to the beam divergence angle and inversely proportional to the beam waist width. Therefore, the smaller the M2 factor, the smaller the error caused by the laser particle sizer. Therefore, it is very important to study the influence of M2 factor on the measurement result of laser particle sizer.
