Excited mercury atoms in an electrodeless discharge are exposed to high-power radiation at 5289 Å obtained by frequency-doubling the output of a Q-switched Nd : glass laser. A very weak line is detected at 4250 Å and described to a Raman transition from the 63 P2 to the 63 P1 state.

The case in which resonance interaction between radiation and the medium is determined by collective processes is considered. It is shown that for low radiation energies the interaction results in modulation of the electromagnetic field. The de-excitation time of the nonequilibrium medium due to collective processes is also determined. (auth)
