Ys. Qiu et al., Incoherent-to-coherent conversion using an induced self-pumped phase conjugator or a mutually pumped phase conjugator, OPT ENG, 39(4), 2000, pp. 1044-1046
Incoherent-to-coherent converters using an induced self-pumped phase conjug
ator and using a mutually pumped phase conjugator are demonstrated in a Ba1
-xSrxTiO3 crystal. Resolution of 28 line pairs/mm has been obtained for the
two incoherent-to-coherent converters. An notable advantage for the latter
converter is that the converted image with amplified intensity can be obta
ined easily. (C) 2000 Society of Photo-Optical instrumentation Engineers.
