Abstract

A two-quantum spontaneous emission of a medium with periodically time-dependent optical length is considered. The emission results from the zero-point fluctuations of the medium. Usually this emission is very weak. However, it can be strongly enhanced if the resonant condition omega₀ = 2.94 c/l₀ is fulfilled (here omega₀ and l₀ are the frequency and the amplitude of the oscillations of the optical length of the medium, respectively, and c is the speed of light in vacuum).
