E. Fiordilino et V. Miceli, SPECTRUM CONTROL IN HARMONIC-GENERATION FROM A 2-LEVEL ATOM AT LOW LASER INTENSITY, Laser physics, 6(6), 1996, pp. 1204-1208
We show (1) that harmonic generation can be obtained by a two-level at
om driven by an almost resonant laser held of intensity much lower tha
n that used in current experiments and (2) that the emitted spectrum c
an be efficiently determined by varying the detuning between laser and
atomic transition.
