A laser resonator device (1), provided with an optical system (2), an optical waveguide (3), a first resonance element (4), and a driving device (5). The optical system (2) collects light onto an optical axis (A). The optical waveguide (3) includes a gain medium. The gain medium emits light having a wavelength range greater than a single wavelength. The optical waveguide (3) causes light emitted by the gain medium to enter the optical system (2). The first resonance element (4) has an entry surface (4a) for reflecting some of the light collected by the optical system (2). The driving device (5) varies the position of the entry surface (4a) of the first resonance element (4) along the optical axis (A). Light having a wavelength corresponding to the position of the entry surface (4a) of the first resonance element (4) returns from the first resonance element (4) to the optical waveguide (3) via the optical system (2). Laser light (6) is thereby oscillated. |
