PURPOSE:To enable oscillating wave length to be controlled by equipping a first mirror, which moves in the direction to let a laser medium flow and circulate, and a second mirror, which is arranged opposite to this first mirror, and shifting either of the first and second mirrors in the directions of a resonant axis so as to control the resonator length. CONSTITUTION:When a driving part M is started, the rotor 11C inside a pigment cell 3 is rotated through a rotary shaft 11D, whereby a pigment solution 5 inside the pigment cell 3 flows and circulates by the rotor 11C. In this condition, an exciting beam 4 excites the pigment solution 5 inside the pigment cell 3, and the beam generated by this resonates between the first and second mirrors 11A and 11B, and is oscillated as a pigment laser beam 11. Moreover, by shifting the second mirror 11B in the direction of a resonant shaft by a resonator length control means, the resonator length changes, whereby the oscillating wave length is controlled. |
