Abstract
Abstract This disclosure is directed to a device which generates an enhanced third harmonic light wave of the neodymium laser by the introduction of anomalous dispersion into a liquid medium to produce phase matching of the interacting waves, and applications thereof which depend upon the state of polarization of the incident laser radiation. The invention described herein may be manufactured and used by or for the Government of the United States of America for governmental purposes without the payment of any royalties thereon or therefor.
