Accurate determination of the incident beam power density in laser damage experiments depends critically on an evaluation of the beam cross section at the surface of the target sample. This in turn requires accurate positioning of the sample in relationship to the focal point of the beam-converging lens. A simple method has been developed for determining the focal position without removing either lens or sample. Only a nominal value of the focal length is required as an input.
