Light Emitting Diodes and Semiconductor Lasers | SpringerLink
A brief comparison of Eqs. 7.1a and 7.4 shows that the main difference between the spontaneous emission and stimulated emission is that the former is an arbitrary emission process whilst the latter is coherent. Therefore the emitted photons are in the same phase and have the same polarisation and the same frequency.
