The intensity patterns produced by a Gaussian (TEM<sub>00</sub> mode) laser beam propagating in the vicinity of the optical axis of α-iodic acid have been photographed. Densitometric profiles for different polarization conditions have been obtained. The theory of Portigal and Burstein has been extended to permit a quantitative comparison between theory and experiment for conical refraction in noncentrosymmetric crystals.
