Abstract:
A semiconductor laser device comprising:a semiconductor laser chip having a first electrode and an optical resonator which has a longitudinal axis extending in a first direction, wherein said optical resonator includes an emitting portion to emit laser light in said first direction parallel to said longitudinal axis; a laser sustaining material having an electrode on a surface thereof where said semiconductor laser chip is mounted; a solder layer in electrical connection with the electrode formed on said laser sustaining material; wherein the first electrode of said semiconductor laser chip is connected with said solder layer of said laser sustaining material, and wherein at least said solder layer of said laser sustaining material has a extended portion that extends from at least one end face of the semiconductor laser device in the first direction of the optical resonator to the outside of the optical resonator of said semiconductor laser chip, wherein the solder layer that extends from at least one end face of the semiconductor laser device in the first direction to the outside of the optical resonator is bent in a direction leading away from said longitudinal axis so that said extended portion is offset in a lateral direction from said longitudinal axis so as to avoid interfering with said laser light emitted from said emitting position.
