Og. Calderon et al., THE ROLE OF THE SOLVENT VISCOSITY ON THE SPATIOTEMPORAL INSTABILITIESOF LARGE-APERTURE DYE-LASERS, Applied physics letters, 73(5), 1998, pp. 557-559
Local intensity fluctuations in a large aperture dye laser have been m
easured for several solvent viscosities. A decrease on the relative fl
uctuations amplitude as the solvent viscosity increases is found. From
a theoretical approach, we show that the intensity fluctuations follo
w the same behavior as the molecular polarization orientation driven b
y the laser field. (C) 1998 American Institute of Physics.
