Abstract
We exploit the high second-order susceptibility of the organic crystal -(4–nitrophenyl)-L-prolinol to accomplish, through a cascaded second-order process, wavelength conversion of a signal pulse (from 1.16 to ) under the action of a pump pulse (at ). In a 2.8-mm-thick crystal, wavelength conversion with unit gain was obtained with a pump peak intensity as low as . At low intensities, in the limit of negligible conversion where the cascading effect can be described through an effective third-order susceptibility, we derive , which is larger than the nonresonant of conjugated polymers or semiconductors.
