| Abstract: | The principle and key technique for formatiOn of a pure laser induced population grating in dye solution is presented, and the electronic lifetimes in the excited stales of dyes have been measured with this grating. The experiments exptess that the laser beam can aimulbocously produce the orientation grating and population grating as well as the thermal grating in dye solution. The formation of population guting depends not only the polarization of exciting light field but also the geometry of experimental configuration. It is clearly indianaed that population grating should gain dominance over others for obervation of longitudinalrelaxation in a molecular system. |
