Abstract
The characterization and application of a new source of incoherent light for studies of ultrafast processes in condensed matter is described. It is based on the stimulated Raman effect in monomode optical fibers and has a coherence time of ∼80 fs. As an application, we have measured the homogeneous dephasing time of CdSxSe1−x‐doped glasses and obtained a value of 14±4 fs for above‐gap excitation at room temperature.Keywords
