Abstract :
An investigation of thermal effects in a high power 3-5μm solid state laser pumped with different pump beam transverse profiles is carried out by COMSOL software based on the finite element method, and the temperature of the crystal center where the Super-Gaussian distributed light projected area is 81.8°C, and is bigger than that of Gaussian pump light mode and top plane pump light mode.
