Expression for the probability of the spontaneous emission of high-orderharmonics when the emitter phases are synchronized and are obtained in theregion where the multiphoton approximation is applicable to the description ofthe ionization of an atom (where the adiabaticity parameter satisfies gamma >1). The dependence of this probability on the main parameters of the pump waveand the atomic medium is established. Criteria for observing emission areformulated with the consideration of phase locking.
