Abstract:   (6533 Views)
In this work we simulate the effect of thermal lensing on propagation of partially coherent flattened Gaussian beam within Nd:YAG laser crystal. At first, an analytical solution of heat equation for an LD end-pumped Nd:YAG laser was derived. Then, an explicit and analytical formula for the propagation of partially coherent FGBs through a paraxial optical ABCD system is introduced. Finally, based on the temperature and equation of propagation, we can investigate the propagation of FGB’s in a thermal lens medium.
Keywords: partially coherent flattened Gaussian beam, ABCD system, Thermal lens medium
