title: Infrared optical constants of polycrystalline boron nitride.
abstract: Effective optical constants of boron nitride have been determined at CO(2) laser wavelengths. Waveguiding losses are evaluated to be 3 x 10(-4) cm(-1) for a 2-mm-inner-diameter guide showing the suitability of boron nitride for waveguide laser construction.
