Design of a High Power 10-KW Solid-state Heat Capacity Laser and the Thermal Management

The simulation results of a 10-kw heat capacity slab laser are presented. two different schemes for optical pumping with highpower laser diodes are investigated. the simulation of optical pumping using zemax software demonstrates a uniform pump distribution within the laser slabs. additionally, the temperature distribution in the laser slab is examined using comsol. the findings for two distinct laser designs reveal that increasing the slab dimensions reduces the temperature distribution and thermal issues. furthermore, cooling schemes indicate that the cooling phase of a 10-kw hcl falls within the range of 20-40 seconds. a comparison of water and air cooling of the optically pumped slabs during the cooling phase demonstrates that water cooling is more efficient than air cooling. the simulation results confirm that the proposed laser will be an efficient device for laser material processing. a focused 10-kw hcl laser will melt the steel sheet after less than 1 s at 1490 k.
