摘　　要：结合飞秒激光超强、超快、超稳、宽频、广谱、相干的特点,介绍了其相应的技术应用情况:应用超快特性的微观物理、生物、化学、信息、通信等;以超强应用为对象的材料加工、制备、电子对撞加速器、受控核聚变等;以超稳特性应用为对象的光频测量、长距离测量、光钟等,并简介了光钟。Combining with the features of femtosecond laser, such as ultrahigh strength and peak power, ultrarapid pulses, ultralhigh steady, wide frequency range, self coherent, its application are introduced. It can be used to physics, biology, chemistry, information, and communication. It is applied to materials manufacture, electrons accelerating, nuclear control etc. and it also can be used in the optical frequency measurement, remote distance measurement, optical clock, and so on. Finally, both the optical clock and its application are described.
