Abstract
Frequency doubling of a 684 nm laser diode in a first-order periodically poled LiTaO3 is presented. Controlling the side growth of the domain inverted region during high-voltage pulse application, a uniform nonlinear grating with a period of 1.7 μm and 50% duty cycle was fabricated over 10 mm interaction length in a 150 μm thick LiTaO3 substrate. A 342 nm wavelength of harmonic ultraviolet light was generated in a single pass through the domain-inverted structure.
