Abstract
Hollow cones of second-harmonic light may, under certain conditions, be produced in nonlinear crystals in the process of optical second-harmonic generation. This effect is caused by the mixing of the central laser beam with a weak off-axis radiation field of the same frequency. Under these conditions noncollinear phase matching (NPM) occurs in a locus of directions defining a hollow cone. Equations have been developed describing NPM in negative uniaxial crystals, and the NPM hypothesis has been verified experimentally. A technique is described for characterizing the phase-matching properties of materials based on this result.
