Anomalous Dispersion phenomena have been investigated as to their applicability to rapid deflection of laser beams. The deflection technique consists of varying the refractive index of a suitable material through a wavelength shift of its dispersion curve. Research on the feasibility of the technique has been carried out for the 6328 A CW gas lasers with the following target objectives 30 K cps deflection rates, 1000 resolution elements, 10 degree deflection angle and less than 10 absorption loss. The results of the investigation show that beam deflection techniques by anomalous dispersion techniques are not practical at present because materials cannot be found that satisfy the conflicting requirements of high ionic density and oscillator strength and narrow linewidth.
