Propagation of a pair of ultrashort coherent pulses in a V-type medium is studied. Both pulses are supposed to be resonant with corresponding atomic transitions. It is shown that the resonant character of the atom-field interaction yields “pulse locking,” in which two pulses propagate with equal group velocities. Additionally, in the presence of Raman inversion, the system exhibits resonantly enhanced gain for the probe pulse. These two effects add together to decrease the pump laser threshold intensity by orders of magnitude in comparison with conventional (far-off-resonant) Raman laser schemes.
