An optical kit for forming an optical system including an external resonator of a laser light source that outputs laser light, the optical kit comprising:
- a base including a main surface;
- a light source holding part provided on the main surface and configured to hold the laser light source;
- and
- a holding part provided on the main surface and configured to hold the optical system,
- wherein the optical system includes
- a corner reflector constituted by a reflective diffraction grating configured to diffract laser light emitted from the laser light source and is incident from a first direction and configured to reflect 0th-order diffraction light in a second direction intersecting with the first direction and a mirror configured to reflect the diffraction light from the reflective diffraction grating in a third direction different from the first direction and the second direction, and
- a first opening member and a second opening member arranged in the third direction to form an optical opening through which the diffraction light from the corner reflector passes in order,
- wherein the holding part has
- a reflector holding part configured to hold the corner reflector,
- a first opening member holding part configured to hold the first opening member, and
- a second opening member holding part configured to hold the second opening member,
- wherein the reflector holding part includes a first mechanism that enables adjustment of an optical axis of the diffraction light in each of the reflective diffraction grating and the mirror,
- wherein, in the third direction, the first opening member holding part is positioned closer to the reflector holding part than an emission surface of the laser light of the laser light source held by the light source holding part, and
- wherein, in the third direction, the second opening member holding part is positioned closer to a side opposite to the reflector holding part than the emission surface of the laser light of the laser light source held by the light source holding part.
An optical device in which an optical system including an external resonator of a laser light source configured to output laser light is formed, the optical device comprising:
- a light source holding part provided on a predetermined surface of the optical device and configured to hold the laser light source;
- and
- a holding part provided on the predetermined surface configured to hold the optical system,
- wherein the optical system includes
- a corner reflector constituted by a reflective diffraction grating configured to diffract laser light emitted from the laser light source and is incident in a first direction and configured to reflect 0th-order diffraction light in a second direction intersecting with the first direction and a mirror configured to reflect the diffraction light from the reflective diffraction grating in a third direction different from the first direction and the second direction, and
- a first opening member and a second opening member arranged in the third direction to form an optical opening through which the diffraction light from the corner reflector passes in order,
- wherein the holding part has
- a reflector holding part configured to hold the corner reflector,
- a first opening member holding part configured to hold the first opening member, and
- a second opening member holding part configured to hold the second opening member,
- wherein the reflector holding part includes a first mechanism that enables adjustment of an optical axis of the diffraction light in each of the reflective diffraction grating and the mirror,
- wherein the first opening member holding part is positioned closer to the reflector holding part than an emission surface of the laser light of the laser light source held by the light source holding part in the third direction, and
- wherein the second opening member holding part is positioned closer to a side opposite to the reflector holding part than the emission surface of the laser light of the laser light source held by the light source holding part in the third direction.
