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).
