PROBLEM TO BE SOLVED: To enhance accuracy in adjustment, and obtain a highly efficient dye laser as a result by performing the adjustment of the optical axis of a dye laser beam not with a pilot beam but with an actual dye laser beam. SOLUTION: This device is equipped with a dye multistage amplifier 100, where one coloring matter laser oscillator 3 and at least two dye laser amplifiers 4, 5, and 6 are connected in series, a solid-state laser device 1 which emits a laser beam for excitation so as to excite each dye laser amplifier 3, 5, and 6, an optical fiber 2 which transmits the laser beam for excitation emitted by this solid-state laser device 1 to the dye laser amplifiers 4, 5, and 6, a shut-off means 14 which is provided between this solid-state laser device 1 and the dye laser multistage amplifier 100 and intercepts the laser beam for excitation, and an opening and closing controller 17 which controls the opening and closing of the shut-off means 14. |
