S. Woutersen et al., GENERATION OF INCOHERENT MIDINFRARED PHOTON-ECHOES WITH PARAMETRICALLY DOWNCONVERTED LIGHT, Optics letters, 21(19), 1996, pp. 1579-1581
We present a demonstration of mid-infrared photon echoes generated wit
h parametrically downconverted incoherent light. The photon echoes gen
erated in this way enable one to study the dynamics of vibrations in t
he 1.5-4.0-mu m wavelength region with subpicosecond time resolution.
