ABSTRACT:
A nozzle for a free jet dye laser wherein the nozzle orifice has an adjustable convex contour to permit realization of precisely plane parallel sides in the central jet region. A jet of this precision is desired to support a high quality laser beam for use in laser enrichment apparatus. The precise planar characteristic of the central portion of the jet is achieved by a narrowing of the central portion of the nozzle orifice. A set of adjustment screws are provided to define the specific contour of the narrowing to insure that the sides of the free jet are precisely plane parallel. A system is shown for detecting the degree to which the sides are plane parallel so that an optimum adjustment in the orifice can be achieved.
