According to the principle of laser and a large number of experimental data proved and also considering the influence of the ignored spontaneous emisson, we study the abnormal phenomenon that the Nd: glass rod which was longer than the optical pump cavity is optically amplified without pumping. The theoretical result is almost the same as experimental result.
