Abstract
The nonlinear properties of the ternary ferroelectric barium fluorides permit noncritical phase matching in the vicinity of 1.06 microns at room temperature. The crystals can tolerate powers of up to approximatey 10.sup.9 watts/cm.sup.2 and may be used as the essential element in second harmonic generators. These devices operate at room temperature without any need for sophisticated temperature control.
