- Each plate-like member cancels the warp and suppresses the warp, and even if the Peltier element 2 including the joining member 3 is warped, the base 5 and / or the restraining member 22 are less likely to warp, and the beam splitter.
- the optical axis shift between 8 and the etalon 9 hardly occurs. Further, as described above, not only the suppression of warpage due to the thermal expansion of the base 4 and the base 5 but also the suppression member 22 so as to compensate for the warpage caused by the Peltier element 2, the joining member 3, the base 4 and the base 5. May be selected. Thereby, wavelength lock control can be performed with high accuracy.
- the suppressing member 22 can be disposed at a place where an optical element such as the beam splitter 8 on the base 5 is not disposed.
- a shape corresponding to the temperature distribution on the base may be taken so as to give a large suppressing effect to the suppressing member 22.
- the thicknesses of the base 4, the base 5, and the suppressing member 22 are determined by the joining state between the plate-like members and the expansion coefficient. That is, the thicknesses of the adjacent plate-like members are set so that the multiplication value of the volume of the surface where the plate-like members are in contact with the linear expansion coefficient substantially matches.

The end side and the end side on which the beam splitter 8 and the etalon 9 are mounted are not joined to the joining member 3.
- the region where the semiconductor laser element 6 is mounted on the base 24 is in a cantilever structure and is in a floating state, and the beam splitter 8 and the etalon 9 on the base 25 corresponding to the base 5 are mounted.

- the connecting portion between the Peltier element 2 and the base 24 is only at the central portion, the warp of the joint surface of the Peltier element 2 itself affects only the central portion, even if the Peltier element 2 is warped. Even if it occurs, the influence of the warp of the Peltier element 2 on the plywood structure including the bases 24 and 25 is minimized. In this case, the linear expansion coefficient between the bases of the plywood structure may be simply taken into consideration.

- Comparative Example 1 a Z-direction displacement of about 5 ⁇ m is generated at the center.
- the Z direction displacement of about 10 ⁇ m is relatively generated. Therefore, in the first and second comparative examples, the amount of displacement in the Z direction can be reduced as compared with the conventional example.
- the Y direction angle of the etalon 29 located in the center is substantially 0, whereas in Comparative Example 2, the Y direction angle of the etalon 29 located in the center is Y of the beam splitter 8. It is almost the same value as the direction angle and is tilted in the same direction. That is, in Comparative Example 2, since the displacement of the beam splitter 8 and the etalon 29 has the same inclination, the relative displacement amount (relative displacement angle) between the beam splitter 8 and the etalon 29 is extremely small. I understand that.
- the Y-direction displacement angle of the beam splitter 8 is 0.19 °
- the etalon 29 has a Y-direction displacement angle of 0.01 °.
