The development of high power fiber laser and technologies are covered in this thesis. The first part of the thesis simulates the signal gain spectrum in an erbium-ytterbium fiber amplifier, which can be implemented in fiber laser systems to generate high power output. The second part proposes the use of gain-guided (GG) optical fibers to achieve high power mode-locked fiber lasers. The spatial-temporal pulse propagation in the GG fiber is simulated; self- focusing, and self-phase-modulation in this type of fiber is studied. The third part discusses phase- locked fiber laser designs. Self-imaging in optical fibers is simulated; the results provide a guide to the phase-locking fiber laser system design. The last part of the thesis investigates cylindrical vector (CV) beams generation from fiber laser system using a birefringent crystal. Radial and azimuthal polarization output can be switched very easily in this fiber cavity design. More interestingly, lasing with...
