A research team led by Prof. Gao Xiaoming from the Hefei Institutes of Physical Science of the Chinese Academy of Sciences ...
Raman spectroscopy is a widely used measurement technique for this purpose. When a laser beam is projected onto molecules, ...
Researchers from IIT Kharagpur have developed a 'zero-threshold Raman laser' that could revolutionise nanoscale laser technology ...
named after Sir C.V. Raman who discovered it in 1928. It involves the scattering of monochromatic light, usually from a laser in the visible, near infrared, or near ultraviolet range. The technique ...
Raman spectroscopy is an analytical technique which can be used to identify the pigments used in a painting. A low powered laser is directed onto the surface of an object or painting and the light ...
Raman Spectroscopy Laser Systems (785nm, P>500mW) High performance diode laser system (single frequency, single mode, up to 1 W, 785 and 980 nm + other wavelengths on request) Single mode fiber ...
Writing in Optics Letters, David Spence and his co-workers from Macquarie University in Australia report the first picosecond pulse, mode-locked diamond Raman laser emitting at 573 nm (ref.
What was the impact of your first continuous-wave silicon Raman laser? When we started working on the silicon laser two years ago, we took a different route. Most people had attempted to create a ...
Braud and colleagues report that several approaches are currently being investigated in a bid to meet the challenge, for example using complex combinations of crystals in Raman laser designs, or by ...
A Raman pump laser is typically stationed at the end of a fiber run and pumps backward several kilometers to amplify signals through that region. See EDFA. THIS DEFINITION IS FOR PERSONAL USE ONLY.
A Zero Threshold Raman Laser refers to a type of laser based on the Raman scattering effect allowing highly efficient light generation with very low power requirements.
