Abstract:
1. A laser device comprising: a laser element having an emission surface from which laser light is emitted; an optical fiber having an end part facing the emission surface; and a supporting member for supporting the optical fiber, the supporting member having a bonding pad on which the optical fiber is fixed by solder, the supporting member including: a plate part having a width extending in a width-wise direction, a first longitudinal end and a second longitudinal end in a longitudinal direction perpendicular to the width-wise direction and having (i) a first main surface on which the bonding pad is provided at the first longitudinal end of the plate part and (ii) a second main surface opposite to the first main surface in a vertical direction perpendicular to the longitudinal direction and the width-wise direction; and a columnar part having a first vertical end and a second vertical end in the vertical direction and fixed to a heat releasing member on the first vertical end, and the second vertical end of the columnar part being attached on the second main surface of the plate part at the second longitudinal end of the plate part such that the second main surface and the heat releasing member face each other while being spatially away from each other.
