Abstract

Theoretical studies of the efficiency of cw optically pumped far infrared lasera (OPFIRL) tend to neglect transversal variations of the pump-intensity (see e.g. passes through the low absorbing cavity. Realistic pump field distributions appear to be different due to the common practice of focussing the pump beam through a small coupling hole, thus introducing large intensities of the "primary beam" that will always dominate the overall intensity profile /2/. The specific consequences of radially varying pump fields will be discussed in two steps.
