Characterization of Transmission Gratings in Photorefractive Materials
POSTER
Abstract
Measuring the transmitted and diffracted beam powers while writing and probing the grating with a power meter is a simple characterization method of transmission gratings. The transmission grating writing process consists in doping a photorefractive material as lithium niobate crystal using an argon laser beam of 514.5 nm wavelength. This transmission grating is probed using a helium-neon 632.6 nm laser beam, following Bragg’s conditions. By measuring the transmitted and diffracted power from both experiments, the power meter will show if there is a correct characterization of transmission gratings.
