Single frequency linearly polarized DFB fiber laser source

摘要

A distributed feedback fiber laser formed in non-polarization maintained ytterbium doped fiber has been studied, its parameters have been measured in dependence on pump power and pump wavelength. Laser performance has been compared for two regimes of fiber heat sinking. Under conditions of sufficient acoustical insulation no polarization mode competition have been observed thus single polarization can be achieved with external polarizer.
