The double end-pumped utilizing two different pumping profiles, namely, Gaussian and super- Gaussian beam profiles are adopted in this simulation. In addition, four different super- Gaussian beam profiles (N = 4, 6, 10, 30) have been studied and compared with the Gaussian (N = 2) pump profile. At Gaussian pumping power of 40 W (20 W for each face), maximum center temperature is observed for each face of the two end-pumped faces were found, and start to decrease in the super-Gaussian case as the exponent factor N increases. The thermal lensing effect strongly depends on different factors, namely, power of the pump source, and distribution profile of the pump through the laser medium geometry. Therefore, the double-end-pumped method may be considered as important to reduce temperature gradiant in the laser rod while choosing the type of pumping profiles. 2018-12-25T06:10:08Z 2018-12-25T06:10:08Z 2018-10 Article International Journal of Nanoelectronics and Materials, vol.11(4), 2018, pages 473-480 1985-5761 (Printed) 1997-4434 (Online) http://dspace.unimap.edu.my:80/xmlui/handle/123456789/57728 http://ijneam.unimap.edu.my en Universiti Malaysia Perlis (UniMAP)
