Brillioun Scattering

Contact: Maddury Somayazulu
Location: R-129

Brillouin Light Scattering Spectroscopy (BLS) consists of a Sandercock- type Fabry-Perot interferometer, an Ar-ion gas laser operating at 514.5 nm as the light source, and a control unit, including photon-counting system with a photomultiplier detector. In GL, Brillouin scattering technique combined with the diamond anvil cells has been intensively used in a wide research area: geophysics, mineral physics, liquids, dense gases, phase transitions, and ferroelectrics. This facility is supported by the CDAC (Carnegie/DOE Alliance Center) and Carnegie Institution. Contact Person: Maddury Somayazulu, Location: Research Building R129, Restrictions: Special Training Required- Safety Hazards: (1) Laser light radiation may affect the Vision if the laser light was observed directly without any eye protection. Protective eyeglasses are required when laser is operated. (2) High Voltages, the power supply for the laser control unit utilizes high voltage (340V). The power supply and the laser control unit are not allowed to open for any reason without consultation with Maddury Somayazulu
