Abstract:
A laser diode module comprising:a laser diode; an optical system including an optical fiber and a lens portion, said optical system being configured to receive and transmit a beam emitted from said laser diode through said lens portion to said optical fiber along an optical axis; a base configured to support said laser diode and at least a portion of said optical system; and a bottom plate configured to support said laser diode, said optical system, and said bases, wherein said base includes a solid structural support member configured to prevent warping of said base, said structural support member being elongated along said base in a direction generally parallel to said optical axis, and wherein said base comprises a laser diode mounting member and a holder mounting member mounted to said laser diode mounting member, said laser diode mounting member supporting said laser diode and said holder mounting member supporting a portion of said optical system, said holder mounting member being made of a material having a thermal conductivity value lower than a thermal conductivity value of said laser diode mounting member.
