Abstract:
A novel concept of corner pumping has been developed. The corner-pumped slab design allows long absorption length and symmetric conduction cooling, making it particularly suitable for high-power quasi-three-level lasers. A corner-pumped Yb:YAG slab laser has been demonstrated for the first time. A preliminary experimental result shows that the laser produces 202 W of cw output power with 1400 W of incident pump power. PACS 42.55.Xi; 42.60.Da; 42.60.Pk
