Abstract

A direct B-integral measurement, and SPM compensation method in fiber optic CPA systems is demonstrated. For a pair of input pulses, the chirped nature of the amplification transforms a nonlinear phase change into a temporal amplitude change resulted in a satellite side pulses generation. The SHG autocorrelation measurement of these satellite pulses is directly correlated to B-integral value. Then the accumulated SPM is removed by precompensation of the spectral phase. The degree of compensation again confirmed the described B-integral measurement result.
