Since its birth, the nanograting structure in glass induced by a single femtosecond laser has attracted extensive attention and becomes a hot topic in the field of femtosecond laser interaction with matter, which has gained major progress in both basic research and application exploration after more than ten years of development. The research status of femtosecond laser induced self-organized nanogratings in glass is reviewed. As for the major influence parameters, formation mechanism, application exploration, and other aspects of nanogratings, the main progress in recent five years is specifically introduced. In addition, as for this topic, the critical issues at present are commented and the future development is prospected.
