Three exponentials are needed to fit the decrease in scattered light intensity with increasing delay time between pump and probe pulses. The decay time of the fastest component varies between 270 and 120 fs if the grating fringe spacing is reduced from 15.5 to 7.8 ,um at constant dye concentration (
The picosecond transient grating technique has been used to study the rotational reorientation of CGo in various solvents: in toluene 7 + 1.5 ps, o-dichlorobenzene 10.3 f 1.5 ps, o-xylene 13 f 2 ps and in decalin 3.5 + I .5 ps. The data obtained cannot be described by hydrodynamic Debye theory. Roug
A new burn-probe sequence is utilized uith non-photochemical hole burning to study the optical dephasing of impurities in polymer films. For crcsyl violet in pol)?inyl alcohol the temperature dependence of dephasing is close to linear in the range studied. A burn time dependence of hole widths is ob
