Generation of incoherent mid-infrared photon echoes with parametrically downconverted light
Opt. Lett. , Volume 21 p. 1579- 1581
We present a demonstration of mid-infrared photon echoes generated with parametrically downconverted incoherent light. The photon echoes generated in this way enable one to study the dynamics of vibrations in the 1.5-4.0 -μm wavelength region with subpicosecond time resolution.
