Piezooptics of crystals

In this paper the effects of mechanical stress on the refractive, absorptive and the rotatory properties of crystals have been considered with particular emphasis on the role of crystal symmetry. Stress-induced optical activity and the photoelastic behaviour of transparent, weakly absorbing and metallic crystals have been discussed. Piezooptia of polycrystalline media has also been briefly dealt with

Faraday effect and birefringence-I

Approximate formulæ correlating the decrease in Faraday rotation with birefringence have been derived and these have been verified by experiments on strained glasses and plastics. It is found that for small values of birefringence, the decrease in the Faraday rotation is proportional to the square of the total birefringence. For values of the birefringence of λ/30, the decrease in the rotation is less than 1%. The Verdet constant in birefringent solids can be accurately determined provided sufficiently thin specimens are taken such that the total birefringence is small. Finally it is shown that the decrease in the Faraday rotation can itself be used as an accurate measure of the birefringence in strained solids

Faraday effect and birefringence-II

The Verdet constant and the magneto-optic anomaly for corundum for light travelling along the optic axis have been determined for the wavelengths λ5,893, λ5,461 and λ4,358. The Verdet constant has the values V5893=0·0210', V5461=0·0240' and V4358=0·0381' minutes per cm. per Oersted and γ has a value of 0·64. Accurate measurements have also been made for directions of propagation inclined to the optic axis and it is found that the Verdet constant does not sensibly change for an inclination of about 15° away from the optic axis
