Expressions are derived for the calculation of the central frequencies f 1,2 0 , and the frequency band δf of wide-band anomalous acoustooptic interaction in crystals of arbitrary symmetry class. The effect of the difference between the ray and phase velocities of the diffracted light on the magnitude of f 1,2 0 and δf is pointed out. Results are presented of the computed acoustooptic quality factor M2, the frequencies f 1,2 0 , δf and the electromechanical coupling constant for the tangential field kD for cuts of LiNbO3 crystals ensuring maximum diffraction efficiency. It is shown that the maximum M2=22.10−18 cgs units in this crystal is attained in the case of anomalous light diffraction by the slow shear wave propagating in the Y-120‡ direction. To the same cut there corresponds the maximum KD=0.685. The design of anomalous acoustooptic deflectors developed is described. Experimental results are presented.
