Vermeulen and colleagues 1 have now proposed a solution to reduce heat generation in powerful optically pumped Raman lasers that generate wavelengths beyond the reach of other lasers. Their ...

Schematic representation of Raman spectroscopy. After the sample (molecule) is exposed to an intense beam of monochromatic light in the frequency range of visible, near-infrared or near-ultraviolet ...

Over the last decade Raman spectroscopy has become established ... Improvements in instrumentation, including better lasers, optics, charge-coupled device cameras and computer processing, has ...

When selecting a Raman spectrometer, the primary consideration should be the wavelength of the laser light that will be utilized to excite the sample. Since the technique is related to the vibrational ...

A laser optical pulse ... broadening towards longer wavelengths, depicted as an orange output beam (right). This nonlinear phenomenon is caused by the Raman effect associated with the rotations ...
