Abstract
In order to satisfy the measurement requirement of ultraviolet pulses in a large laser system,with a single mode ultraviolet fiber propagating and sampling the signal,the characteristics of the ultraviolet pulse propagating in linear media were analyzed in theory,and the factors affecting the measurement of the pulse shape were reviewed systematically.The pulse profiles were measured after the ultraviolet pulse propagating a single-mode pure silica fiber.It is shown that single-mode ultraviolet fiber is a preferable medium for nanosecond pulse.An ultraviolet fiber is not suitable for long distance transmission considering the great loss and the limitation of the sensitivity of the detector.These results are significant for the design of pulse profile measuring system of high power laser facility.
