Coherent anti-Stokes Raman scattering from small volumes.
We have used coherent anti-Stokes Raman scattering spectroscopy to resolve the Raman Q-branch line [Q (2) at 2987.18 cm(-1)] of dueterium gas contained in a 60-microm-diameter glass sphere. The 60-microm spheres contained only 10(+13) molecules at standard temperature and pressure; this made it possible to study gases that in larger quantities would be too dangerous or expensive to use.
