Abstract
A source of linearly polarized light having a wavelength selected from the range of about 500 to 1100 nanometers provides light into one end of an optical fiber. A nonlinear crystal of the type that mixes the frequency of light passing therethrough is positioned adjacent the other end of the fiber. The fiber transmits light from the source to the crystal which increases its frequency up to 100%, dependent upon crystal selection, thereby providing light in the 250-550 nanometer wavelength range. Adjusting the radial orientation of the crystal with respect to the fiber optimizes conversion of light to the 250-550 nanometer range.
