Modelling of Ar-Hg Electrodeless Lamps

A self-consistent model of high-frequency electrodeless lamps with internal coils is developed. Radial distributions of the plasma parameters are obtained. Mercury lines with wavelength of 435.8nm and 365nm are measured to testify the model. Based on the model, the population of resonance state 6³P1 of mercury in dependence on the argon pressure and driving frequency are calculated. It is shown that the population of 6³P1 of mercury is larger when the argon pressure is between 26.6Pa and 53.2Pa. Meanwhile the driving frequency has little influence on the population of 6³P1.
