Influenced laser-induced plasma on Raman scattering of water cluster
激光诱导等离子体对水团簇受激拉曼散射的影响

The stimulated Raman Stokes and anti-Stokes scattering of water is studied of by the 532nm laser. The experimental results show that: the laser is focused on the water, the plasma of water is generated when the pump energy is 4mJ; the Stokes line intensity of water OH stretching vibration and the Stokes line bandwidth of it are increased, as the pump laser energies are from 5mJ to 15Mj, and the center wavelength of Stokes become blue-shift; the anti-Stokes line of water OH stretching vibration is generated, when the pump laser energy is 15mJ. The experimental phenomena are explained by the laser-induced plasma enhances stimulated Raman scattering of water cluster, the results are according with the theory. This research provides the theory of Raman laser that water is used to be the work matter.
