Incoherent mid-infrared photon echoes with parametrically downconverted light
Laser Chem. , Volume 19 p. 123- 126
We present a simple method to generate mid-infrared photon echoes, using parametrically downconverted incoherent light. The photon echoes generated in this way enable the study of the dynamics of vibrations in the 1.5-4.0 µm wavelength region with subpicosecond time resolution.
