High energy femtosecond fiber chirped pulse amplification system with adaptive phase control
High energy femtosecond fiber chirped pulse amplification system with adaptive phase control
We demonstrate increased peak power from an Yb fiber CPA system operating with strong self-phase modulation by shaping the spectral phase of the input pulses. An adaptive control loop used feedback from the output autocorrelation. We investigated pre-compensation of both SPM phase distortion at high energies, and residual dispersion from mismatched stretcher/compressor technologies at low energies. Phase shaping resulted in improved pulse quality with the autocorrelation peak typically increased by a factor of three compared to unshaped pulses. High-quality 800 fs, 65 µJ recompressed pulses were produced. This technique could benefit a wide variety of fiber amplifier systems and is self-optimising for operation at both low and high pulse energies.

Abstract
We demonstrate increased peak power from an Yb fiber CPA system operating with strong self-phase modulation by shaping the spectral phase of the input pulses. An adaptive control loop used feedback from the output autocorrelation. We investigated pre-compensation of both SPM phase distortion at high energies, and residual dispersion from mismatched stretcher/compressor technologies at low energies. Phase shaping resulted in improved pulse quality with the autocorrelation peak typically increased by a factor of three compared to unshaped pulses. High-quality 800 fs, 65 µJ recompressed pulses were produced. This technique could benefit a wide variety of fiber amplifier systems and is self-optimising for operation at both low and high pulse energies.
