Abstract
Multiple photon echo signals were found to be the reflection of the oscillation structure of the primary echo signals formed by excitation of two-level active centers. Amplitude pulses are of the same length, but their amplitude is different. The length of the pulse is comparable with the delay between them. The primary photon echo of the oscillation structure is shown to exist in the intervals (-t1,t1) and (-2t1,2t1). It was established that under certain correlation between the amplitudes of exciting pulses the oscillation signal structure becomes asymmetric. That is why in the regime of square-law detection of the primary photon echo signal its asymmetry oscillation structure is observed in the form of frequent of isolated signals (multiple photon echo), the distance between them being equal to the pulse length.© (2001) COPYRIGHT SPIE--The International Society for Optical Engineering.
