Total internal reflection in gain medium slab
The problem of light propagation through a slab of gain medium is studied in terms of the transfer matrix pole distribution. Identifying the lasing by the existence of the poles in the upper half-space of the complex frequencies, we demonstrate that under the condition of total internal reflection lasing may be observed at a finite thickness of the slab; further increase in the thickness results in the quenching of lasing. However, in the latter case the amplification of reflected wave is possible.
