摘要：

Optical phase-conjugation properties of the backward-stimulated radiation from a two-photon-pumped frequency-upconversion lasing medium are studied. The gain medium is a new dye solution pumped with similar to 11-ns and similar to 1064-nm laser pulses; a highly directional and phase-conjugate backward-stimulated emission at similar to 616-nm wavelength could be obtained with a net conversion efficiency of similar to 10%. The spectral, temporal, and output-input characteristics of this kind of stimulated emission are presented in detail. The phase-conjugation properties of the backward-stimulated emission have been demonstrated by both the far-field (beam-divergence) measurement and the near-field (image-reconstruction) measurement. The wave-front reconstruction behavior is, not perfect, especially under a larger aberration influence. (C) 1998 Optical Society of America.
