文摘
The nonlinear thermal conductivity of the laser material that appears in the ceramic Nd:YAG laser was analyzed. The nonlinear thermal conductivity equation describing the pump power was derived from the measured focal length of the thermal lens on the ceramic Nd:YAG. As the pump power increased, the thermal conductivity decreased, reaching a value of 5.2 W/mK at a temperature of 384.9 ¡ãC and a pump power of 15.3 W.
