## An energy transfer laser experunent IS reported m which coumarm I acted as the energy donor and coumarin 31-t as the hsng acceptor At an optunum concentration of lo-' hI for the coumann I and 10m3 hl for the coumarin 314 in methanol, the mL\ture was Xwice as efficient as a laser than cuumarm 31
Kinetic analysis of an energy transfer dye laser is presented. 'lie laser gain function depends on the molecular parameters and on ?he concentrations of both the donor and acceptor. For the lo? signal limit the gain shows linear dependence on either the donor or the acceptor concentrations for a fix
The Iaser and fluorescence behavior was studied for the mixed dye system contairdng various concentrations of 3,3'ðylthiacarbocyanine iodide and rhodamine 6G. A new way of confming the occurrence of energy transfer is presented on the basis of the reabsorption effect.
