A Novel Technique Applied to Low Repetition Narrow Band Pulse Polarization Stabilization
The all-fiber and all-solidified technique was installed to the front end of the next generation high power laser system. Appropriate control to the polarization was required to maintain the stabilization of the fiber system. In order to maintain low repetition narrow band pulses′ polarization stabilization, a novel active control technique applied to single mode fiber laser system which worked with low repetition narrow band pulses was proposed. A root-mean-square of 1% and a peak to valley ratio of 7% stability were achieved, when the pulse polarization stabilizer based on this novel technique was used to 1.5 ns pulses at repetition above 100 Hz. The new polarization stabilizer was applied to fiber front end of the second generation high power laser system. The performance index was better than national ignition facility (NIF), and this technique could be used to control the polarization of the narrow-band and low-repetition system actively.
