Laser module including jointly arranged isolator and fiber sleeve

Laser module comprising:

• a first housing, said first housing being a hermetically sealed module housing;
• a semiconductor laser device arranged within said first housing;
• a plurality of pins extending from said first housing, at least some of said pins being arranged for connecting the laser device to electronic circuitry external to said first housing;
• a support arranged within said first housing, said semiconductor laser device being arranged on said support;
• the laser module further comprising
• a fiber sleeve for holding an optical fiber, said fiber sleeve being arranged on said support for supporting said optical fiber in a fixed relation to the laser device, for allowing light from the laser device to enter said optical fiber;
• a lens arranged on said support for focusing light from the laser device onto an end of said optical fiber;
• an isolator for preventing light from being reflected back towards the laser device;
• wherein
• said isolator and the fiber sleeve are jointly arranged within a second housing, said second housing being an integral holder holding both said isolator and fiber sleeve.
