abstract

A travelling wave optical parametric generator based on a ZnGeP2 crystal, pumped by an actively mode-locked Cr:Er:YSGG laser ((lambda) equals 2.8 micrometers ) has been used for the study of non-linear-optical phenomena in (InGa)As/(AlGa)As and GaAs/(AlGa)As Multi Quantum Wells (MQWs) which had intersubband absorption features in the range (lambda) approximately 4..10 micrometers . Using a two-color pump-probe scheme a dynamic spectral hole burning effect has been observed for the first time, confirming the inhomogeneous nature of MQW absorption line broadening in these samples.
