Sum frequency generation vibrational spectroscopy (SFG-VS) is an intrinsically surface-selective vibrational spectroscopic technique based on the second-order nonlinear optical process. Since its birth in the 1980s, SFG-VS has been used to solve interfacial structure and dynamics in a variety of research fields including chemistry, physics, materials sciences, biological sciences, environmental sciences, etc. Better understanding of SFG-VS instrumentation is no doubt an essential step to master this sophisticated technique. To address this need, here we will present a Tutorial with respect to the classification, setup layout, construction, operation, and data processing about SFG-VS. We will focus on the steady state Ti:sapphire based broad bandwidth SFG-VS system and use it as an example. We hope this Tutorial is beneficial for newcomers to the SFG-VS field and for people who are interested in using SFG-VS technique in their research.
和频振动光谱学（SFG-VS）是一种基于二阶非线性光学过程的固有表面选择性振动光谱技术。自 20 世纪 80 年代诞生以来，SFG-VS 已被用于解决化学、物理、材料科学、生物科学、环境科学等各种研究领域的界面结构和动力学问题。更好地了解 SFG-VS 仪器无疑是掌握这项复杂技术的关键步骤。为了满足这一需求，我们将在这里介绍一个关于 SFG-VS 的分类、设置布局、结构、操作和数据处理的教程。我们将重点介绍基于稳频钛宝石的宽带宽 SFG-VS 系统，并以此为例。我们希望这个教程对 SFG-VS 领域的新手以及对在研究中使用 SFG-VS 技术感兴趣的人有所帮助。
