  • Abstract
    An accurate method for measuring the focal lengths of weak lenses formed in the laser media due to the pumping sources is reported. The optical power in the wings of a Gaussian beam is a sensitive function of the spot size. The change in the spot size and consequently, the focal length, is measured by measuring the change in the optical power in the wings, using a stop to block the central part of the probe beam.
