Enhanced-Dynamic-Range Single-Shot Measurement of Nanosecond Optical Pulses Based on Fiber Pulse Replication Loop
A new method is proposed to enhance dynamic range single-short measurement of nanosecond optical pulses. A fiber pulse replication loop system is developed to generate temporal replicated pulse train with an exponential decay curve, and the effective loop gain is 0.955. By compensating each pulse to the same amplitude and averaging 18 pulses in the front of the replicated pulse train, the dynamic range can be improved more than 2.74 times. It can meet the need of 1001 high dynamic range inertial confinement fusion pulse measurement by combination PIN diode in conjunction with oscilloscopes.
