Abstract

The design and characterization of the laser beams used in NPLI's Cesium Fountain experiment is described in the present paper. A 1-D photodiode array based instrument was indigenously developed for this dedicated purpose. Major advantages over the conventional 2-D array based instruments include stand alone operation, reduced cost and computational requirements. This instrument specifically finds applications for direct measurement and analysis of broad laser beams (FWHM similar to 20 mm).
