摘要： Fiber delivery systems are desirable to provide convenient delivery of an output beam from a laser system to a target distanced from the source. For ultra-short pulse lasers, a limiting factor in fiber delivery is the dispersion of the optical fiber. A fiber delivery system for ultra-short pulses that uses a photonic crystal fiber to Fprovide the appropriate dispersion is described.
