Summary
This article presents the design and experimental validation of a compact auto-correlator built using fiber optic devices for measuring ultra-short laser pulses, which is particularly useful for characterizing fiber lasers. The authors addressed challenges related to polarization effects in the fiber interferometer and the frequency-doubling crystal, as well as the coupling efficiency of fiber collimators. They successfully measured the pulse width of a mode-locked fiber laser, demonstrating the feasibility and advantages (compactness, compatibility with fiber systems) of this fiber-based auto-correlator.
