Enhancing stimulated Raman scattering of water and heavy water lattice vibration by laser induced plasma

Enhancing stimulated Raman scattering of water and heavy water lattice vibration by laser induced plasma

Guang Pu Xue Yu Guang Pu Fen Xi 33(8): 2031-2034

Stimulated Raman scattering was studied in water and heavy water using pulse laser at the wavelength of 532nm, not only obtaining the stimulated Raman of O-H and O-D stretching vibration, but also obtaining the stimulated Raman lattice vibration. When the laser energy was 130 mJ, the low frequency Stokes and anti-Stokes 313 cm(-1) line of water could be observed; When the laser energy was 160 mJ, the low frequnecy Stokes and anti-Stokes 280 cm(-1) line of heavy water could be observed. The results were explained by physics mechanism of laser induced plasma.
