Abstract
Intraband linear-circular multiphoton dichroism of far infrared absorption in p-Ge has been observed for thefirst time. Previously this nonlinear optical phenomenon was observed only under the valence-conductioninterband electronic transitions induced by IR or visible-range radiation. Experimentally, the dependencies of theoptical transmission and the photon drag effect on the FIR radiation (X = 90 gm) intensity and polarisation havebeen investigated in p-type Ge crystals. A polarisation dependent sign inversion of the photon drag effect withincreasing radiation intensity has been also observed.
