pump intensity

The inhomogeneous distribution of gain coefficient is inevitable because of the inhomogeneous distribution of pump light intensity in laser medium. So it is necessary to include gain coefficient distribution in the resolution of the self-reproducing field pattern.

这样光强分布的不均匀必然导致增益分布的不均匀，因此，在考虑自再现模时有考虑增益系数分布状态的必要。
