63Frequency-resolved optical gating — In optics, frequency resolved optical gating (FROG) is a derivative of autocorrelation, but is far superior in its ability to measure ultrafast optical pulse shapes. Further, it can determine the phase of the pulse.In the most common… …
64GRENOUILLE — Grating eliminated no nonsense observation of ultrafast incident laser light e fields (GRENOUILLE) is an ultrashort pulse measurement technique based on frequency resolved optical gating (FROG). The somewhat frivolous acronym was chosen because… …
65Holographic data storage — is a potential replacement technology in the area of high capacity data storage currently dominated by magnetic and conventional optical data storage. Magnetic and optical data storage devices rely on individual bits being stored as distinct… …
66Robert N. Hall — (b. December 25, 1919) is an American engineer. He demonstrated the first semiconductor laser, and invented a type of magnetron commonly used in microwave ovens. He also contributed to the development of rectifiers for power transmission.Hall was …
67Peter L. Hagelstein — Professor Peter L. Hagelstein is a principal investigator in the Research Laboratory of Electronics (RLE) at the Massachusetts Institute of Technology (MIT). He received the B.S. and the M.S. in 1976, and the Ph.D. in electrical engineering in… …
