Abstract
A package for a high power semiconductor laser comprising a hermetically sealed container filled with a dry gaseous medium containing oxygen. The presence of oxygen in the laser atmosphere is counter to standard practice in the art which teaches the use of an atmosphere of a dry inert gas.
Claims11
A packaged high power semiconductor laser comprising:
- a semiconductor laser;
- and,
- a hermetically sealed container surrounding said laser and filled with a gaseous medium wherein the oxygen content is greater than 100 ppm.
A high power semiconductor laser packaged in a hermetically sealed container filled with a dry gaseous medium including oxygen in an amount effective to prevent impurity depositions on the facet structure.
A method for packaging a high power semiconductor laser comprising:
- fixedly positioning said laser in a container;
- introducing a gaseous medium including oxygen, in an amount effective to prevent impurity depositions on the facet structure, into said container;
- and,
- hermetically sealing said container.
A device for pumping an optical waveguide amplifier fiber comprising:
- a high power semiconductor laser;
- and,
- a hermetically sealed container enclosing said laser and filled with a gaseous medium including at least 100 ppm oxygen.
