摘　　要：飞秒激光在强场激光物理、超快化学动力学、微结构材料科学和生命科学等不同领域有着广泛应用。Yb:KGW晶体以其优异的综合性能适于作为飞秒激光器的增益介质,因此研究Yb:KGW飞秒激光器具有重要意义。自2000年瑞士研制出世界第一台被动锁模Yb:KGW飞秒激光器以来,国内外多家机构开展了Yb:KGW飞秒激光器的研究。主要报道了国内外Yb:KGW飞秒激光器的最新进展。目前能实现的最短脉冲宽度是100fs,与理论值的47fs还有一定的差距。Femtosecond laser has many applications in different areas, such as the strong-field laser physics, ultrafast chemical kinetics, the microstructure of materials science, and life science. The Yb：KGW crystal with its excellent performance is so suitable to be femtosecond laser gain media that the research of Yb： KGW femtosecond laser is of great significance. Since Switzerland-developed the world＇s first passively mode-locked Yb： KGW femtosecond laser in 2000, there have been a number of domestic and foreign institutions dedicating to the research of Yb： KGW femtosecond laser. The latest progress of the Yb： KGW femtosecond laser at home and abroad is reported. The shortest pulse width is 100 fs. There＇s still a big gap between experimental value and the theoretical value of 47 fs.
