Claim:
1. A semiconductor laser device comprising: a base; a semiconductor laser element provided above the base; a lid provided over the base and housing the semiconductor laser element, the lid having a recess formed in an upper portion of the lid with the recess being defined by a lateral surface and a bottom, and the lid having a through-hole formed in the bottom of the recess; a support member disposed in the recess and having a through-hole disposed above the through-hole of the lid, a diameter of the through-hole of the support member being smaller than a diameter of the through-hole of the lid, the support member having a coefficient of thermal expansion that is different from a coefficient of thermal expansion of the lid, and the support member having a lateral surface spaced apart from the lateral surface of the recess; a wavelength converting member supported in the through-hole of the support member; a holding member fixed to the lid and holding an upper surface of the support member; and a buffer material disposed in at least a part of a space between the lateral surface of the recess and the lateral surface of the support member.
