Generazione di Seconda Armonica per Quasi-Phase-Matching Random in Tantalato di Litio con Poling Periodico

2009

We experimentally observed and explained bulk Second Harmonic Generation via Random Quasi-Phase-Matching, derived from a periodically poled Lithium Tantalate sample with a randomly patterned mark-to-space-ratio.

First-Order Quasi-Phase-Matched Blue Light Generation in Surface-Poled Ti:Indiffused waveguide

2004

The application of surface periodic poling method for first order quasi-phase-matched (QPM) second harmonic generation (SHG) in Ti:indiffused lithium niobate channel waveguides, was investigated. On a 2.5 μm wide channel waveguide which was periodically poled with a period of 2.47 μm for TM waveguide mode interaction, efficient SHG was observed. The CCD camera was used for monitoring the near-field waveguide mode profiles of both the fundamental and second harmonic waves. The potential of surface domain inversion for efficient nonlinear waveguide interactions was shown after the production of 6 mW of continous-wave blue radiation.
