Paper Abstract

A method of checking the laser beam spatial intensity is described. It is based on the measurement of the radiation power density of the light entering the ring area whose diameters are changeable. From derived power density distribution the usefulness of the tested laser for a given application can be concluded and the value of the laser beam diameter, estimated as a function of the radiation power level, can be calculated. A practical measurement set-up and its use for investigations of diode laser modules is presented. Because of its simplicity and low operation cost, the described approach can be particularly suitable for testing lasers destined for such proposes as alignment, medium transmittance measurements and others.
