Measurement of acousto-optic interaction in Germanium in the far infrared

  • W. Dürr
  • W. Schmidt


Acousto-optic interaction in a Germanium Bragg cell, which was operated as acoustic resonator, was measured at 119 μm relative to 10.6 μm. The figure of merit of the material was found to be approximately 20% higher in the far infrared. The performance of various acousto-optic materials in the far infrared is briefly discussed.
