Dual-Clad Ytterbium-Doped Fiber Amplifiers

Narrow-linewidth ytterbium-doped dual-clad fiber amplifiers are an attractive technology for high power phased arrays. They offer many advantages including high gain and ease of thermal management. However, they also have many disadvantages including significant amplified spontaneous emission, temporal instabilities, and parasitic non-linear effects. I will present results of modeling and experiment for a fiber master oscillator and fiber amplifier. I will discuss temperature effects, self-pulsing, and stimulated Brillouin scattering.
