Abstract
High-power CO 2 laser radiation at 1045 cm-1is shown to enhance the room temperature transmission of p-Ge in a spectral region extending at least from 3000 to 4000 cm-1. The interaction arises from radiation-induced changes of the hole populations within the three valence bands. Ultrafast nonradiative relaxation is responsible for the very large interaction bandwidth observed and allows the prediction of a minimum switching time of 1 ps.
