Abstract
Precision interferometry, deep-space coherent communication, and efficient external cavity resonant frequency conversion experiments share several laser requirements. These systems require a several-watt output power laser that is: efficient, reliable, TEM00 mode, polarized, and single frequency. The most important consideration in building a laser-diode-pumped, solid-state laser is efficient use of pump radiation. End pumping uses pump radiation very efficiently, but requires a high brightness pump source.1 A side-pumped laser configuration is less efficient, but removes the brightness requirement, Side pumping together with a rectilinear geometry produce a laser with low thermal distortions.2
