摘要：

A closed system of equations for spherical microresonator modes and populations of energy levels of two-photon excited molecules placed in a resonator and exposed to a femtosecond laser pulse is derived. The threshold of transition of spontaneous emission into stimulated one (in the superfluorescence mode) in a microparticle is established with allowance for the microparticle morphology and laser pulse duration.
