The effect of fourth-order coherence on ultrafast modulation spectroscopy(UMS)with phase-conjugation geome-try(PCUMS)in a cascade three-level system is investigated using chaotic and phase-diffusion models.It has been...
Stationary photorefractive self-pumped phase-conjugation with one four-wave-mixing interaction region,stimulated by the photorefractive amplified backward scattering,is obtained in LiNbO3:Fe crystals,in which the stro...
Based on the first part of this paper (Science in China, 33(1990), 982—995), further research has been done on quasi-equivalence relation and asymmetrical character of axisymmetrical phase-conjugatlon resonator(PCR)....
Based on 'the matrix theory for the propagation of a scalar light wave in a system consisting of plane screens (cylindrical coordinates)' proposed by one of the authors (1981), the propagation of the self-consistent f...
During the last decade, phase-conjugation mirror (PCM) and phase-conjugation resonator (PCR) have interest to many authors in that they can be used to improve the quality of laser beams. For a laser using conventional...
