The dependance of the output power of cw dye lasers on the pump power and the system-and stream parameters is calculated and experimentally tested. It was found that the pump power for a given system is limited to a critical value due to the influence of thermal inhomogeneities. This critical pump power is predominantly dependant on the dye solvent, the flow velocity, the focussing of the pump laser and the stability range of the dye laser system. Possibilities for the reduction of the thermal inhomogeneities are discussed and attainable output powers are calculated.
