Temperature Distribution in a Gaussian End-Pumped Nonlinear KTP Crystal: the Temperature Dependence of Thermal Conductivity and Radiation Boundary Condition

“…The amount of heat loaded in the crystal determines the cooling systems needed [16]. If the crystal size is not appropriately selected (relative to pump power), the thermal effects may destroy it [19]. Furthermore, effective cooling systems play a pronounced role in decreasing the detrimental thermal effects [20].…”
