Paper Abstract

A more useful model for calculating temperature distributions in kilowatt ytterbium-doped double-clad (YDDC) fiber lasers is proposed. Radiation, a major mode of heat transfer, is taken into account when the thermal conduction equations are solved for temperature distributions in the fiber tube. The results are compared with the ones obtained without considering radiative heat transfer. The presented model gives a qualitative explanation of the real operating conditions of YDDC fibers.
