Resonators with Variable Internal Lenses
摘要
InThermal lensing solid state laserSolid state lasers materials the heat generated by the pump process and cooling of an outer surface will lead to a temperature profileTemperature profile that exhibits gradients in direction of the heat flow. For a side-pumped rod with radius b and length ℓ, and under the assumption that the thermal conductivityThermal conductivity is a constant and the heat is homogeneously distributed, a radially parabolic temperature profileTemperature profile T(r) is formed.
