The transition between the transient and the stationary regimes of sti
mulated Raman scattering is examined computationally for pulses with a
sharp initial rise. We find that the transient-regime predictions are
useful for times less than T-2 regardless of the pulse duration and t
hat the stationary-regime predictions become useful only for times muc
h greater than T-2. (C) 1996 Optical Society of America.
