A. Mcinnes et J. Richards, THERMAL EFFECTS IN A COPLANAR-PUMPED FOLDED-ZIGZAG SLAB LASER, IEEE journal of quantum electronics, 32(7), 1996, pp. 1243-1252
The properties of a coplanar-pumped folded-slab laser under the influe
nce of thermal lensing have been modeled and measured. It is shown tha
t despite the formation of a strong astigmatic lens within the slab, t
he results can be used to design resonators capable of good TEM(00) pe
rformance, suitable for a wide variety of applications. Good agreement
is found between modeling and measurement of slab and laser parameter
s. Using a novel technique, the fraction of absorbed pump power conver
ted to heat has been measured under diode-laser pumping.
