提出了一种提高纳秒光脉冲单次测量动态范围的方法,其中光纤脉冲复制环用来产生时域上幅度呈指数递减的脉冲复制串,有效环增益为0.955。经软件补偿脉冲复制串使其具有相同的幅度,然后累加平均前18个脉冲,能够将注入的单发纳秒光脉冲动态范围提高2.74倍,这样就可以实现利用光电探测管和示波器对100:1高对比度的惯性约束核聚变(ICF)脉冲测量。
A method to improve the single-shot dynamic range of nanosecond optical pulse is proposed. The optical fiber pulsing loop is used to generate pulsed replicas with an exponentially decreasing amplitude in the time domain. The effective loop gain is 0.955. Software-compensated pulsed replica strings with the same amplitude and cumulative average of the first 18 pulses can increase the dynamic range of the injected single nanosecond light pulse by 2.74 times. This allows the use of a photodetector and oscilloscope for 100: 1 high contrast inertial confinement fusion (ICF) pulse measurement.
