Thermal lens correction of a diode-pumped Nd:YAG laser of high TEM(00) power by an adjustable-curvature mirror.
Highly efficient TEM(00)-mode laser power of 11.5 W was obtained by the diode-array side pumping of a Nd:YAG rod. We maintained efficient laser operation at all pump powers by correcting for the changing thermal lens with an adjustable-curvature mirror.
