Two kinds of efficient acousto-optically phase-matched non collinear optical SHG are predicted in Te for the incident optical wave at lO,6p in. The first one is calculated with the shear acoustic wave propagating along the X localized by the three Euler angles cp=° , 0=1 500, 1600 , 4 450, and is interpreted as being due to mixing of the incident optical wave and the acousto-optically scattered wave. The other SHG is observed with the same slow acoustic shear wave and is due to the mixing ot the two acousto-optically scattered optical waves. It is shown from absolute SHG calculations and corresponding SF10 measurements previously reported in Te, that the non linear optical coefficient which governs these high efficiency SHG interactions is d1 2 = 920 x 10- '2mfV The corresponding SHG efficiencies are two orders of magnitude larger than the previously reported phase-matched non-collinear SHG in Te for the same input optic power and acoustic conditions. Another highly efficient SHG configuration in Te is discussed as well as the possible application of these techniques to a parametric oscillator and to a fast infrared two dimensional optical inverter array.
