Active Instantaneous-Phase Equalization and Amplitude Control in Pulse-Bursts in a Narrow-Linewidth Divided-Pulse Yb-Doped Fiber Amplification System

We demonstrate active inter-pulse amplitude control and intra-pulse instantaneous-phase equalization in bursts of 50 1-ns pulses in a 1.15-mJ, B~16 rad narrow-linewidth linearly-polarized divided-pulse Yb-fiber amplification system and theoretically compute 90% coherent pulse-stacking efficiency.
