  "abstract": "An optical module includes a first base member, a second base member disposed spatially away from the first base member, a first laser disposed on the first base member and configured to emit red light, a second laser disposed on the second base member and configured to emit light with a color other than red, and a first electronic cooling module disposed in contact with the first base member and configured to adjust a temperature of the first laser.",
  "claims": [
    "1. An optical module comprising: a first base member; a first submount disposed on the first base member; a second base member disposed spatially away from the first base member, wherein the second base member is not in direct contact with the first base member; a first laser disposed on the first submount and configured to emit red light; a second laser disposed on the second base member and configured to emit light with a color other than red; a first electronic cooling module disposed in contact with the first base member and configured to adjust a temperature of the first laser; and a base supporting the first base member with the first electronic cooling module disposed between the base and the first base member, wherein the first base member comprises a first region, a second region, and a third region; the optical module further comprises a first lens disposed on the first base member in the first region; the first submount is disposed on the first base member in the third region; a thickness of the first base member in the second region is greater than a thickness of the first base member in the first region; and a thickness of the of the first base member in the third region is greater than the thickness of the first base member in the second region.",
    "2. The optical module according to claim 1, wherein the second laser is configured to emit green light or blue light.",
    "3. The optical module according to claim 1, further comprising a second electronic cooling module disposed in contact with the second base member and configured to adjust a temperature of the second laser.",
    "4. The optical module according to claim 3, further comprising a protective member that surrounds the first base member, the second base member, the first laser, the second laser, the first electronic cooling module, and the second electronic cooling module.",
    "5. The optical module according to claim 1, wherein optical axis heights of the first laser and the second laser from a reference surface match each other.",
    "6. The optical module according to claim 1, further comprising: a second submount disposed directly on the second base member, wherein the first submount is disposed directly on the first base member; and the second laser is disposed on the second submount."

  "description_excerpt": "The present disclosure relates to an optical module. The present application claims the priority based on Japanese Patent Application No. 2016-248768 filed on Dec. 22, 2016, the entire contents of which are incorporated herein by reference.\n\nOptical modules including semiconductor light-emitting devices disposed in a package have been known (e.g., refer to PTL 1 to PTL 4). Such an optical module is used as a light source for various apparatuses such as display apparatuses, optical pickup apparatuses, and optical communication apparatuses.\n\nPTL 1: Japanese Unexamined Patent Application Publication No. 2009-93101\n\nPTL 2: Japanese Unexamined Patent Application Publication No. 2007-328895\n\nPTL 3: Japanese Unexamined Patent Application Publication No. 2007-17925\n\nPTL 4: Japanese Unexamined Patent Application Publication No. 2007-65600\n\nAn optical module according to the present disclosure includes a first base member, a second base member disposed spatially away from the first base member, a first laser disposed on the first base member and configured to emit red light, a second laser disposed on the second base member and configured to emit light with a color other than red, and a first electronic cooling module disposed in contact with the first base member and configured to adjust a temperature of the first laser.\n\nFIG. 1 is a schematic perspective view illustrating a structure of an optical module according to a first embodiment.\n\nFIG. 2 is a schematic perspective view illustrating an internal structure of the optical module according to the first embodiment.",
