Observation of the near transform-limited high-resolution tunable far-ultraviolet light

This paper studies the near transform-limited high-resolution tunable far-ultraviolet light which is generated by narrow-band tunable light both theoretically and experimentally. It presents the theoretical work on conversion efficiency of sum-frequency, which is restricted by phase-matching angle, walk-off angle and phase distortion and so on, and conducts an experiment to check this work successfully. Also the origin of chirp of a dye laser is analysed.
