Lasing in a gain slab as a consequence of the causality principle

Transmission of a semi-infinite light pulse through a slab of an gain medium is considered. It is demonstrated that, in the presence of lasing, the Fresnel formulas yield a finite field distribution violating the causality principle: lasing in the slab begins starts the moment at which the pulse fro...
