Abstract
An experimental setup for the fiber Bragg gratings (FBGs) inscription by use of Talbot interferometer has been described in this paper. A KrF excimer laser system Master Oscillator–Power Amplifier CL-7550 (Optosystems Ltd, Russia) was used as the UV radiation source in the experimental setup. In order to control laser beam quality, thus to provide FBGs effective writing, the laboratory setup includes: spectral width control system, based on Fabry–Perot interferometer; laser beam energy distribution control system; monitoring system of laser pulse energy density on the optical fiber; and control system of optical fiber to the laser beam relative position. FBGs of type I inscription results in a single-pulse and multi-pulse modes are presented.
