Abstract
Thin-rod Yb:YAG active element is investigated in the terms of thermal effects, gain, lasing and scalability through the theoretical and experimental analysis. Low temperature, great gain and huge thermal lens are found in the thin rod. Lasing with 6 W average power and 45 % slope efficiency is obtained.
