Second-harmonic generation-frequency-resolved optical gating analysis of low-intensity shaped femtosecond pulses at 1.55 {mu} m
We illustrate observation and characterization of medium- and low-intensity shaped ultrashort pulses at {lambda}=1.55 {mu}m through single-shot geometry (multishot-average) second-harmonic generation-frequency-resolved optical gating. The pulses are shaped by amplitude filters in the Fourier plane of a compact folded shaper. Sensitivity to pulses with energies of less than 20 pJ and high dynamic range is reported for this configuration. Application of this method to the propagation of {approx}170-fs pulses through a 50-m fiber link is also illustrated. (c) 1999 Optical Society of America.
