In addition, because Raman lasers require an initial laser input, they are most effective as a wavelength shifter ... Figure 1: Raman shift and diamond Raman laser design. In many materials ...

A small fraction, however, is inelastically scattered, experiencing a change in energy and wavelength. This phenomenon, known as Raman scattering, occurs due to the vibrational energy levels of the ...

Longer wavelength excitation lasers have a lower ... In this case, a 680 nm excitation laser translates to a Raman shift of 2000-4000 cm-1. The probe filters are chosen to enable excitation ...
