Abstract

Disk active elements of various doping and geometry are investigated for heat sources and lasing. Yb:YAG of 10% doping has strong overheating under high excitation level. The phenomenon is most severe for thin disk, while composite disk shows much less overheating. The latter case shows less lasing efficiency but better small-signal gain.
