Experimental and theoretical study of the performance of optically pumped cesium vapor laser as a function of the pump-to-laser beam overlap Conference Paper uri icon

abstract

  • We report on the results of an experimental study of Ti: Sapphire pumped Cs laser and theoretical modeling of these results, where we focused on the influence of the pump-to- laser beam overlap, a crucial parameter for optimizing the output laser power. Non monotonic dependence of the laser power (optimized over the temperature) on the pump beam radius was observed with a maximum achieved at the ratio~ 0.7 between the pump and laser beam radii. The optimal temperature decreased with increasing pump beam radius. Maximum laser power> 370 mW with an optical-to-optical efficiency of 43% and slope efficiency~ 55% was obtained. A simple optical model of the laser, where Gaussian spatial shapes of the pump and laser intensities in any cross section of the beams were assumed, was compared to the experiments. Good agreement was obtained between the …
