Abstract

The elliptical beam of a laser diode is collected by a circular aperture decentered with respect to the beam. The fractional optical power collected is calculated and measured as a function of the decentered distance, beam size, and aperture size. The calculation results agree well with the measurement results. An application example of the results is described.
