ABSTRACT:
Apparatus for determining the composition of mercury-cadmium-telluride or other alloy semiconductors by using a four-photon mixing phenomenon. Means are provided for a pair of colinear laser beams of different optical frequencies such that the colinear beams passed through a sample of Hg.sub.1-x Cd.sub.x Te or other alloy semiconductors to produce emissions beams of the original incident optical frequencies and two or more additional optical frequencies formed by an electron spin-flip interaction. A magnetic field means is employed for varying a magnetic field across the sample during passage of the colinear beam from the points substantially below to substantially above the resonant field of the sample to produce a spin-flip signal which has a peak amplitude. Detector means are adapted to receive the emission beams to identify the spin-flip signal peak from which the spin-level splitting factor can be measured. Upon measurement of the spin-level splitting factor, the value for x can be calculated in Hg.sub.1-x Cd.sub.x Te or other alloy semiconductor.
