A system based on CCD to measure laser beam quality was designed and built. CCD was used to measure laser beam diameter at different locations. The collected data samples were then curve fitted to the beam propagation hyperbolic equation. Here the non-linear least squares method was employed to fit the hyperbolic curve
and the results of the fitting procedure yielded laser beam quality
