(a) Schematic diagram of the pump burst and the Stokes burst in the time domain. N: number of pulses in burst. ∆τ: inter-pulse temporal separation. φ: pulse-to-pulse offset phase. Ω R: Raman frequency ...
Raman scattering and Fluorescence emission are two competing phenomena, which have similar origins. Generally, a laser photon bounces off a molecule and looses a certain amount of energy that allows ...
In research published in APL Photonics, the team described using diamond crystals and the Raman effect—where laser light stimulates vibrations in materials and then scatters off those vibrations—to ...
Chandrasekhara Venkata Raman is considered as one of best physicists ever produced by India. Born on November 7, 1888, in Tamil Nadu's Tiruchirapalli, Raman is known for his work in the field of light ...
The Raman effect is based on light scattering. In most instances, light that “hits” a molecule does not interact with it and so the photon does not lose energy. This process is known as elastic ...
(Nanowerk Spotlight) Surface-enhanced Raman scattering (SERS) offers enormous potential for chemical sensing, even though the large nonlinearity of the effect makes reproducible sensing difficult.
Raman microscopy is an analytic technique which uses a standard optical microscope in combination with a Raman spectrometer to visualize samples under high magnification as well as performing Raman ...
With the 2019 Nobel Prize for Physics due to be announced on Tuesday 8 October, Physics World journalists pick their favourite Nobel awards from the past. Here Anna Demming argues the case for the ...
In 1986, under Prime Minister Rajiv Gandhi’s leadership, the Indian government declared February 28 as National Science Day to honor Dr. C.V. Raman’s groundbreaking discovery, the Raman Effect. On ...
