Data:

Fiber 1: 6/125 DCF (core dia/clad dia)

Fiber 2: DCF fiber (Er-Yb doped fiber) 10/125

Excitation: 25W from 980nm laser

Power Dissipation:

1. Heat dissipation of 6/125 DCF = 6.55E+10 W/m^3 in the core

2. Heat dissipation of 10/125 DCF = 2.38E+10 W/m^3 in the core

Regarding plot: with joint offset heat build up plot
