High-power widely tunable thulium fiber lasers.

Applications requiring long-range atmospheric propagation are driving the development of high-power thulium fiber lasers. We report on the performance of two different laser configurations for high-power tunable thulium fiber lasers: one is a single oscillator utilizing a volume Bragg grating for wavelength stabilization; the other is a master oscillator power amplifier system with the oscillat...

Optical Fiber for High-Power Optical Communication

We examined optical fibers suitable for avoiding such problems as the fiber fuse phenomenon and failures at bends with a high power input. We found that the threshold power for fiber fuse propagation in photonic crystal fiber (PCF) and hole-assisted fiber (HAF) can exceed 18 W, which is more than 10 times that in conventional single-mode fiber (SMF). We considered this high threshold power in P...

Mode - locked fiber ring lasers with semiconductor optical

This thesis is on the development of high-speed pulsed lasers at wavelengths around 1.55 m for applications in the fiber optic communications field. The realization of future optical transmission systems and signal processing circuits will require such optical pulse sources, capable of producing picosecond pulses with a low timing jitter at repetition rates of tens or even hundreds of Gigahertz...
