| Abstract: | Composite laser slabs are suggested to reduce thermal effects when laser slabs are pumped by high laser power. The temperature and thermal stress distribution resulted from Finite Element simulation in sing slabs are compared respectively with those in composite slabs using forced convection to cool the slabs. The influence of composite slabs to the highest temperature and thermal stress in slabs is analyzed, and the optimum size of composite slab is proposed. |
