Abstract : This invention relates to optical isolators and particularly to an ultraviolet optical isolator which utilizes a KDP-isomorph for rotating the polarization of ultraviolet radiation in the wavelength range from about 190 to about 350 nanometers. Optical isolators using Faraday rotators have many uses in laser technology, such as for isolating stages of oscillator-amplifier systems and for discriminating against reverse-traveling waves in ring cavities. A Faraday rotator is a device that rotates the angle of polarization of light by using the Faraday effect. The Faraday effect is a magneto-optic effect wherein a magnetic field applied to a Faraday material causes the axis of polarization of the linearly polarized light to rotate.
