In order to solve thermal effect of thermal conductive anisotropic laser medium by LD end-pumped

a thermal model of Nd:YVO4 crystal with adiabatic end faces and cooling circumference was established. Considering that the Nd:YVO4 crystal is a thermal conductive anisotropic material and the output beam of LD coupled by fiber has the characteristic of super-Gaussian distribution

a general analytical temperature field expression of thermal conductive anisotropic laser medium end-pumped by the super-Gaussian beam was obtained by the methods of eigen-function and constant variation. Meanwhile

the temperature field influences of the super-Gaussian beam with different orders

spot radius and powers on the Nd:YVO4 crystal were quantitatively analyzed. The new method for solving heat conductive equation of anisotropic medium has the specialties of smaller calculation amount and higher accuracy. The results show that when the output power of LD is 10W

the transmission efficiency of optical focusing coupler is 82%，the end-face of neodymium doped yttrium orthovanadate crystal with 0.5% neodymium ion doped mass fraction end-pumped by the forth order super-Gaussian beam get a maximum temperature rise of 528.95C. The results can be applied to the design of thermally stabilized cavity of all-solid-state laser with thermal conductive anisotropic laser medium by LD end-pumped

and will play theoretically instructive effects at improving the performance of lasers.
