PROBLEM TO BE SOLVED: To provide a dye laser device that can accurately and stably change the dye solution and output a stable dye laser beam by preventing pulsing change of the flow rate of the dye solution flowing in a piping. SOLUTION: This dye laser device is provided with a piping from discharging or replenishing pumps 11 and 15 for dye solution to flow meters 20 and 21 and a discharging auxiliary bypass circulating route Bo or a replenishing auxiliary bypass circulating route Bi through each pump and each of tanks 18 and 16. Thus, the pulsing flow of the dye solution in the auxiliary bypass circulating route is eliminated and the dye solution is allowed to be passed through each flow meter from each pump in this state, thereby measuring the flow rate of the dye solution. |
