Combing  sky for other Earths: few-cycle laser optics in frequency combs

报告内容

摘  要

Femtosecond laser frequency combs have  revolutionized precision metrology because they provide a broad spectrum of  highly stable and precisely known optical frequencies. This  talk will discuss key ultrafast laser  technologies in implementing broadband visible-wavelength frequency combs  with multi-GHz comb spacing. A prefect application enabled by such frequency  combs is to calibrate astrophysical spectrograph to support the search for  earth-sized rocky exoplanets  (“astro-combs”).

简 介

Guoqing Chang graduated with both Bachelor and  Master degrees from Electronics Engineering department of Tsinghua University  and Ph.D. degree in Electrical Engineering from the Center for Ultrafast  Optical Science at the University of Michigan. After staying at the  University of Michigan as a postdoctoral research fellow for about one year,  he joined the Research Laboratory of Electronics at Massachusetts Institute  of Technology as a postdoctoral research associate. In August 2012, he moved  to the Center for free electron laser (CFEL) at Hamburg (Germany) as the head  of the Helmholtz Young investigator group “Ultrafast Fiber Optics” under the  ultrafast optics and X-Rays division.
