Noncollinear phase-matched four-photon mixing in Hg0.77Cd0.23Te.
We observed phase-matched four-photon mixing in Hgo.77CdO. 2 3Te by using a noncollinear configuration. The observed phase-matching angle is in good agreement with theoretical estimates obtained using Brown's [T. L. Brown, M.S. thesis (MIT Press, 1975)] approach. Phase matching improves the conversion efficiency of the mixing process by an order of magnitude.
