摘要

Two kinds of methods to design multi-segmented slab are proposed and the thermal effects of laser diode end-pumped multi-segmented slab laser are investigated. The temperature and stress distributions in laser crystal have been calculated by FEA. The results proved that the multi-segmented slab had lower temperature peaks, lower mechanical stress peaks and higher the maximum incident pump power for a given length compared with constant doping slab. The multi-segmented slab is beneficial to power scaling of laser diode end-pumped slab laser.
