摘要
超短脉冲激光正在进行着从飞秒 (1fs=10 - 1 5s)向阿秒 (1attosecond =10 - 1 8s)的跨越 ,这一跨越对于激光原理和激光应用来说都有很重要的意义 .文章通过阿秒脉冲与飞秒脉冲比较来介绍超快激光的新前沿———阿秒科学 ,包括阿秒科学的诞生。
In the visible and near infrared region ultrafast lasers have reached a pulsewidth of 3 7fs, which is about one period of the wave. This heralds the new age of attosecond pulses, which have been observed in the XUV region through high-harmonic generation. In this paper, new developments of ultrafast lasers, the possibilities of attosecond pulse generation and potential applications are discussed.
