Abstract
This paper analyzes the effects of thermal blooming on the Far-Field Irradiance Distribution, based upon the steady-state thermal blooming model, which is introduced by Wallace. It uses the method of numerical simulation and gives the relativity between thermal blooming and these parameters, including initial power,the radius and wavelength. The result reveals that a new void dimensional parameter can describe the extent of thermal blooming. When this dimensional parameter decreases, thermal blooming effect becomes more serious. The result can provide theoretic analysis of thermal blooming effect on the Far-Field. In addition, when the wavelength or the radius changes, the result of Wallace model does not accord with the fact. The contradiction reveals the shortcoming of this model.
