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.
