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.

摘要

本研究介绍了一种紧凑、便携式飞秒光纤激光系统，该系统设计用于在均匀填充模式下与SPring-8同步加速器X射线脉冲同步。与传统的固定安装的钛宝石锁模激光器不同，我们的系统利用光纤激光技术为时间分辨光谱学提供了一种实用的替代方案，在可用性、便携性和成本效益之间取得了平衡。包括脉冲表征、定时抖动和频率稳定性测试在内的综合评估显示，中心波长为1600 nm，脉冲能量为4.5 nJ，脉冲持续时间为35 fs，定时抖动小于9 ps，证实了该系统适用于时间分辨光谱研究。这一进展提高了结合同步加速器X射线和激光脉冲的实验的可行性，通过实现更灵活多样的研究应用，做出了重大的科学贡献。
