Abstract:

An attempt was made to observe spin-flip Raman scattering from single crystals of n-type CdTe at liquid-helium temperatures. A 1.06 micrometer NdYAG laser was used as the source of pump radiation, and scattered light was collected and analyzed. A 10-tesla superconducting magnet was used. Although the spin-flip emission could not be observed, the CdTe phonon spectrum was recorded for a number of the samples. Scattering was observed from both the zone-center longitudinal optic LO phonon and from the zone-boundary longitudinal optic plus transverse acoustic LO TA two-phonon process. Back-reflection Laue photographs were taken of the cardinal crystal planes of CdTe. Included is a general discussion of the spin-flip Raman laser and the features which make the device important in the field of laser technology, followed by a brief explanation of Landau-Raman light scattering, the basic principle underlying the spin-flip Raman laser.
