Dr. Peter de Groot of ZYGO discusses advances in optical metrology, addressing complex applications in challenging environments.
Optical frequency combs generated in quantum cascade lasers. The discovered harmonic comb regime produces a spectrum with an intermodal spacing that is 10 to 100 times larger than that observed in fundamental frequency combs (right) enabling completely new applications in this platform. Both types of frequency combs can be generated using the same type of device. (Image courtesy of Jared Sisler/Havard SEAS)
