Abstract
Frequency doubling of a 684 nm laser diode in a first-order periodical ly poled LiTaO3 is presented. Controlling the side growth of the domai n inverted region during high-voltage pulse application, a uniform non linear grating with a period of 1.7 mu m and 50% duty cycle was fabric ated over 10 mm interaction length in a 150 mu m thick LiTaO3 substrat e. A 342 nm wavelength of harmonic ultraviolet light was generated in a single pass through the domain-inverted structure. (C) 1997 American Institute of Physics.
