CO 2 ‐laser produced damping of electron‐hole drop (EHD) luminescence in Ge at laser intensities of 10 4 to 5 × 10 6 W/cm 2 is reported. The observed effect is explained to be due to heating of the EHD by 10.6 μm radiation and driving of e‐h plasma by phonon wind generated during absorption and relaxation of hot nonequilibrium carriers.
