title = "Coherent combining of low-peak-power pulsed fiber amplifiers with 80-ns pulse duration",
abstract = "We investigate the feasibility of pulsed fiber amplifier coherent combining. Therefore, we characterize phase fluctuations in low-peak-power pulsed fiber amplifiers using two different interferometric techniques. These measurements reveal that for low peak-powers, phase fluctuations remain moderate during the pulses. Noticeable phase fluctuations occurring between the pulses can be perfectly controlled using classical continuous-wave-efficient combining techniques. Results of such realization combining two low-peak-power pulsed fiber amplifiers, using classical frequency-tagging coherent combining techniques, are presented. Phase difference measurement is performed between pulses using a small signal leak from the common master oscillator. For the first time to our knowledge, successful coherent combining of two low-peak- power pulsed fiber amplifiers is thereby demonstrated.",
