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~20 mm).
