Laser module and method of manufacturing the same

A method of manufacturing a laser module, the method comprising:

• preparing an optical fiber;
• preparing a laser device operable to emit a laser beam;
• preparing an optical system that couples the laser beam emitted from the laser device to the optical fiber;
• preparing a housing including a base plate and a side wall with an opening formed therein;
• fixing a laser device to the base plate of the housing;
• forming an insulation member including
• a seal portion configured to seal between the side wall and a lead terminal at the opening of the side wall and
• an extension portion that extends continuously from the seal portion to directly contact and support a connecting portion of a lead terminal configured to connect to the laser device;
• sealing between the side wall and the lead terminal at the opening of the side wall with the seal portion of the insulation member while simultaneously supporting the connection portion of the lead terminal with extension portion of the insulation member;
• connecting an end of a conductive wire to the laser device fixed to the housing;
• and
• connecting, by ultrasonic bonding, another end of the conductive wire to the connecting portion of the lead terminal that is supported by, via direct contact, the extension portion of the insulation member within the housing.
