For the propose of improving the anti-jamming ability of a laser pulse shape measuring system,the laser pulse propagation model was established, the linear characteristics of a nanosecond pulse propagating in fibers were analyzed,and factors affecting the pulse transmission characteristics were evaluated systematically.The laser pulse shape was measured with a nanosecond laser pulse propagating through single and multi-mold fiber in different length.The width of the pulse transmitted by the fiber was compared to that of a fraction of the pulse propagating over an air path.The critical condition of pulse broadening acceptable within measuring error was obtained. The conclusion provides guidance to design the laser pulse shape measuring system of the SG-Ⅲ laser facility.
