Abstract

This paper is focused on the investigation of the effect of temperature on the laser amplification process. In case of Ybdoped active media there is a significant dependency of laser and physical properties on temperature that leads to reducing of gain coefficient. Theoretical description and experimental study carried out based on Yb:YAG crystal pumped by high power laser diode. Despite the cooling of the active element, the heating significantly affects at cwpumping regime and determines the shape of gain coefficient dependency on the pump power.
