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 ...

In a new study, researchers at Osaka University have created the world's first compact, tunable-wavelength blue semiconductor ...

This limitation can sometimes be mitigated by using lasers with different wavelengths or employing surface-enhanced Raman scattering (SERS) techniques. Sensitivity Issues: The intensity of Raman ...

Unlike erbium-doped fiber amplifiers (EDFAs), which boost wavelengths in the 1530-1610 ... lengths of signal-transmitting fiber. A Raman pump laser is typically stationed at the end of a fiber ...

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

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 ...

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 ...
