H. Coic et al., 4-WAVE-MIXING WITH PICOSECOND PULSES - ST UDY ON THE TEMPORAL SHAPE OF DIFFRACTED SIGNALS AS FUNCTION OF THE RESPONSE OF THE MEDIUM, Annales de physique, 20(2), 1995, pp. 107-109
We study the temporal shape of the diffracted signal in degenerate fou
r wave mixing experiments with picosecond pulses in the case where the
relaxation time is in the same picosecond range as the pulse duration
.
