Narrow linewidth injection seeded Q-switched fiber ring laser based on a low-SBS fiber

Image Number 3 for United States Patent #7577178.

A narrow linewidth injection-seeded Q-switched fiber ring laser based on a low-SBS optical fiber. High peak powers are achieved through the use of a single-clad erbium doped fiber with an acoustic waveguide. 12.5 .mu.J per pulse (250ns pulse width) is achieved before a weakened form of stimulated Brillouin scattering appears. This laser has the potential to scale to very high power in a low-SBS dual clad fiber.
