ABSTRACT:
A method and associated structures are disclosed for locating a laser beam that has a wavelength outside of the visible portion of the electromagnetic spectrum. The method comprises positioning a sample of a polycrystalline nonlinear frequency converting compound generally linearly downstream from a laser source, and then detecting the emission from the polycrystalline frequency converting compound to thereby identify the position of the original laser beam. In preferred embodiments, the polycrystalline nonlinear frequency converting compound comprises KTP.
