Abstract
A solid laser rod optically pumped is cooled to produce a large thermal gradient extending only along the radiation propagation direction. This thermal gradient results in a reduced average gain cross section, permitting increased energy storage and correspondingly increased laser energy output without thermal optic distortion. In Nd:YAG lasers, a longitudinal cooling profile allows super-radiance at the high gain 1.06 .mu.m transition to be suppressed and useful laser operation to be obtained on lower gain transitions, notably at 0.94 .mu.m or 1.32 .mu.m may be obtained.
