Abstract

The influences of the temperature distribution of a laser medium on thermal effects, especially on the thermally induced diffraction losses, have been investigated in this paper. The results show that the thermally induced diffraction losses are decreasing functions of the pump beam radius for identical mode-to-pump ratios in the laser medium, but it is approximately constant if the real temperature is neglected. Applying this theoretical model to a diode-end-pumped $\mathrm{Nd}\text{:}{\mathrm{GdVO}}_4$ laser at 1342 nm, the pump size was optimized to scale the output power, and the theoretical results are in good agreement with the experimental results.
