More Information
Summary:A laser device that allows its user to change the wavelength of oscillation is obtained. The laser device includes a light source unit provided with a laser element for emitting laser light by forming a laser resonator with an output mirror, the laser element having a rear end surface on which a reflective film is formed; an optical element for determining a wavelength of oscillation emitted from the laser element, on the basis of an angle of the laser light incident on the optical element, the optical element being disposed in an optical path of the laser light emitted from the light source unit; the output mirror for reflecting a part of emission light emitted from the optical element toward the optical element; and angle-of-incidence changing means for changing an angle at which the light emitted from the light source unit is incident on the optical element.
