“…During the last years a large number of works has been concentrated on the problems of collective interactions of atoms with a laser field and with the vacuum of radiation such as superfluorescence (see [1] and Refs. therein), collective resonance fluorescence [2][3][4][5][6][7][8], collective double optical resonance [9], collective Raman scattering [10][11][12][13][14], etc. In the one-atom case the effects due to the fluctuating driving fields have been discussed for resonance fluorescence [12][13][14][15][16][17][18][19], double optical resonance [29] and Raman scattering [20][21][22][23]. Puri and Hassan [8] have studied the effects due to a fluctuating driving laser field in collective spectral and statistical properties of resonance fluorescence.…”
