Paper Abstract

Investigations of the behavior of mercury transitions are reasonable tasks for improvement of different types of light sources as well as for solving environmental problems. Recently, the time behavior of the 546.0 nm spectral line was studied after two step pulse laser excitation of the 73S state via the 63P1 state. A nonmonotonical decay of the population of 73S was observed and was interpreted as a results of the stimulated emission in forward direction of the excitation laser beam. In our experiment we observe the nonmonotonical behavior of the decay of the 546.0 nm spectral line intensity when the 63P1 state is excited by strong pulse laser beam. This behavior is changing when the wavelength of excitation laser beam is tuned around the 253.6 nm wavelength. Some hypothesis for explanation of this behavior is given.
