推进飞秒技术极限──啁啾介质反射镜当今激光物理学主要动向之一是研究和发展飞秒激光源。产生短电磁波的动力来自科学技术诸多领域。超短光脉冲能获得物质状态的“快照”，和随之在微观层次上超快过程的演变。探测半导体载流子动力学、化学键的形成和断裂或生物学光致异... Advancing the femtosecond technology limit ─ ─ chirp dielectric mirror One of the main trends in laser physics today is the research and development of femtosecond laser source. The power to generate short electromagnetic waves comes from many fields of science and technology. The ultrashort light pulse acquires a “snapshot” of the state of matter, and the consequent evolution of the ultrafast process at the micro level. Detection of semiconductor carrier dynamics, the formation and cleavage of chemical bonds or biological ...
