    Raman gain, effectiveg-value and spontaneous spin-flip Raman linewidth in Hg0.77Cd0.23Te (1983)

    Notes: Abstract We report on measurements of spin-flip Raman gain inn-Hg1−x Cd x Te (x=0.23, carrier density 1.0×1015cm−3) as a function of the magnetic field up to 1.6T. The measurements were carried out by a small signal gain technique at a temperature of 1.8 K. Furthermore, the measurements yield lineshapes and linewidths of the spontaneous scattering and allow a precise determination of the effectiveg-value. The highest gain observed is 0.2 cm/W. The band edge value of the effectiveg-value is −93.2 and the widths of the symmetric lines are between 18 and 120 G, depending on the magnetic field.

    Observations of higher-order laser-induced surface ripples on 〈111〉 germanium (1983)
    Springer
    Applied physics 32 (1983), S. 135-140 
    Details
    ISSN: 1432-0630

    Notes: Abstract We report the observation and analysis of higher-order optical diffraction patterns arising from linear combinations of the primary laser-induced gratings or ripples on germanium surfaces. These higher-order surface structures presumably arise from nonlinear interactions between superimposed primary gratings with different grating wave vectors. For gratings produced by normally incident laser beams on Ge 〈111〉 surfaces, the diffraction patterns exhibit a strongly hexagonal symmetry.
