Ramamoorthy Ramesh
Ramamoorthy Ramesh, also published as R. Ramesh, is an Indian-born American materials physicist at UC Berkeley known for solving ferroelectric fatigue and electric-field control of magnetism.
Raman amplification
Raman amplification is a fiber-optic technique that amplifies communication signals by stimulated Raman scattering, turning the transmission fiber itself into a broadband gain medium used in long-haul systems.
Raman amplifier
A Raman amplifier is an optical amplifier that uses stimulated Raman scattering to transfer energy from a pump laser to an optical signal, most often within optical fiber.
Raman cooling
Raman cooling is a laser cooling technique using pairs of laser beams that cools atoms below the single-photon recoil limit, first shown by Kasevich and Chu in 1992.
Raman fiber
Raman fiber is the use of Raman scattering inside optical fibers, either to amplify optical signals in telecom systems or to measure temperature at every point along the fiber.
Raman I. Sujith
Raman I. Sujith, born 1967, is an Indian aerospace engineer and Institute Professor at IIT Madras known for applying dynamical systems theory to thermoacoustic instability.
Raman imaging
Raman imaging is a label-free microscopy technique that maps chemical species by recording a Raman spectrum at each pixel, first demonstrated by Delhaye and Dhamelincourt in 1975.
Raman Lamba
Raman Lamba, Indian cricketer (1960–1998), right-hand opener; 4 Tests, 32 ODIs, 8,776 first-class runs at 53.84, Duleep Trophy record 320; died after on-field head injury in Dhaka.
Raman laser
A Raman laser is a laser whose optical gain comes from stimulated Raman scattering, letting it work in silicon and diamond and emit pump-dependent wavelengths.
Raman mapping
Raman mapping acquires a Raman spectrum at every point of a scanned sample area, assembling the spectra into false-color maps of chemical composition and molecular structure.
Raman microspectroscopy
Raman microspectroscopy is an analytical technique combining Raman spectroscopy with optical microscopy to measure vibrational spectra from microscopic regions, yielding label-free chemical images of live cells and materials.
Raman optical activity
Raman optical activity (ROA) is a chiroptical spectroscopy method measuring the tiny difference in Raman scattering by chiral molecules, first observed by Barron, Bogaard, and Buckingham in 1973.
Raman Piatrushenka
Raman Piatrushenka (Раман Іванавіч Пятрушэнка, Roman Petrushenko), born 1980, Belarusian sprint kayaker; Olympic K4 1000 m gold at Beijing 2008 and four Olympic medals, mostly with K2 partner Vadzim Makhneu.
