Abstract

In the transient interaction between the laser and the material, because of the medium memory effect, the transient response of the stimulated Raman scattering (SRS) to the pulse train of high power laser is different from the effect of the single pulse. This paper discusses the SRS of the pulse laser. The gain expression of Stokes field is given. It can be seen that as the interval T increases, the Stokes's gain decrease. When the pulse number N is large enough, the gain of the Stokes pulse arrives at the steady-state value. The memory effect is the most important fact, influencing the gain of the Stokes field. At the edge of each pulse there is the Stokes field.
