Raman Imaging and Raman Mapping

2009
Raman spectroscopy can be used to non-destructively add image contrast in visualizing structures and dynamics in living systems and materials. Image contrast can be derived from any information contained in Raman spectra, including band intensities, positions and widths.

Intersubband Raman Laser

Applied Physics Letters, 2001
An intersubband Raman laser has been realized in an artificial GaAs/AlGaAs three-level quantum-well structure. A CO2 laser in resonance with the one-to-three level transition is used as the pump, while the lasing emission occurs via the three-to-two level transition.

Multichannel Raman spectroscopy

Analytical Chemistry, 1987
Multichannel detectors have opened up many areas for investigation using Raman spectroscopy. Alan Campion of the University of Texas at Austin and W. H. Woodruff of the Los Alamos National Laboratory describe instrumental aspects of the technique and several applications.

Semiconductor Raman laser

Journal of Applied Physics, 1980
The semiconductor Raman laser has been realized by using a GaP crystal. Pumping is made by a Q-switched YAG laser operating at 1.064 μm. The round-trip loss in the Fabry-Perot resonator is 2% or less. The Raman scattering from LO phonons stimulates in the 〈100〉 direction, while the forward and backward Raman scattering from TO phonons stimulate in the 〈
