Sweeping regimes in a Tm-doped self-sweeping fiber laser

We report on investigation of sweeping regimes in a Tm-doped self-sweeping fiber laser. Influence of the active fiber length and pump wavelength on the wavelength self-sweeping regimes and it's characteristics in the laser is demonstrated. It is expected that the research will help in optimization of output sweeping characteristics as well as in spectral dynamics management with pump power control.
