Abstract

This paper describes the use of an extended, sparsely packed, two-dimensional laser diode-array (ESDA) source for pumping via a compound parabolic concentrator (CPC) pump cavity designed on the edge-ray principle of nonimaging optics. The absorption distribution is investigated in a cylindrical gain medium. Results show that not only does this cavity reduce thermal load but it has a high coupling-efficiency, uniform absorption distribution and gives a higher figure of merit per diode than side-pumped cavity and imaging type elliptical cavity.
