| Abstract: |
This study introduces a compact, portable femtosecond fibre laser system designed for synchronization with SPring‐8 synchrotron X‐ray pulses in a uniform filling mode. Unlike traditional titanium–sapphire mode‐locked lasers, which are fixed installations, our system utilizes fibre laser technology to provide a practical alternative for time‐resolved spectroscopy, striking a balance between usability, portability and cost‐efficiency. Comprehensive evaluations, including pulse characterization, timing jitter and frequency stability tests revealed a centre wavelength of 1600 nm, a pulse energy of 4.5 nJ, a pulse duration of 35 fs with a timing jitter of less than 9 ps, confirming the suitability of the system for time‐resolved spectroscopic studies. This development enhances the feasibility of experiments that combine synchrotron X‐rays and laser pulses, offering significant scientific contributions by enabling more flexible and diverse research applications.
