Improvement of flux uniformity in CO2 laser by laser beam rotation
A method of improving laser flux uniformity has been reported. Laser beam passes through a tilted germanium plate which rotates around the beam. The exit beam from the plate will rotate around its axis. In this way, the spatial uniformity of laser flux can be improved. The relation between rotation parameters and spatial distribution of laser flux intensity has been analysed and the experimental results are in agreement with the theoretical calculation.
