Abstract
An apparatus for producing coherent, continuous wave, ultraviolet light, includes one or more source lasers in the visible or near-infrared frequency range. The apparatus also includes one or more frequency conversion stages. Each of the one or more frequency conversion stages includes one or more reflectors, an optical resonator, one or more waveguide components, or one or more fiber optic components. At least one of the one or more frequency conversion stages includes a huntite-type aluminum double borate nonlinear optical material to produce light having a wavelength between 190 and 350 nm. The huntite-type aluminum double borate material has a composition given by MAl3B4O12, where M is one or a plural combination of elements {Sc, La, Y, or Lu}.
