A brand new method of temperature measurement of optical fibers in lasing condition and nonlinear optical processes is presented. The longitudinal temperature distribution of polymer cladding of active optical fiber doped Yb3+/Er3+ in lasing condition is measured. 3D mathematical model of temperature distribution inside active optical fiber in lasing condition is developed.
