【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。更多还原

【Abstract】 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.更多还原
