Abstract

A method was proposed for measuring the statistical distribution curves of the short term spread of laser beam. The technique were found on the beam width-Time-Amplitude conversion, The precision of the system was of 4. 7eu m. It was determined that the relative fluctuation of the beam width was of 1% in the static air, of 1. 3% in the turbulent air. And when the laser beam passes through the rigion of flame of the alcohol lamp, the relative fluctuation was of 2. 7%.
