Michelson reflector for spectral range stabilization in a self-sweeping fiber laser

Abstract

We report on spectral range stabilization in a self-sweeping laser by adding a fiber Bragg grating (FBG) to output mirror in Michelson configuration. Optimization of the interferometer (reflector) allows us to demonstrate broadband (over 16 nm) self-sweeping operation and reduction of the start and stop wavelengths fluctuations by two and one order of magnitude for start and stop bounds respectively.
