Abstract
An optical assembly includes an optical subassembly containing a prefabricated long wavelength laser optically coupled to a prefabricated short wavelength laser located in a housing. The optical subassembly may be removably installed in the housing in which the short wavelength laser is contained. The short wavelength laser optically pumps the long wavelength laser resulting in a long wavelength laser output. The optical subassembly allows the independent fabrication, optimization and testing of the short wavelength laser and the long wavelength laser.

An optical assembly, comprising:
- a housing;
- a prefabricated electrically pumped short wavelength laser located in the housing and configured to provide a short wavelength laser output;
- a prefabricated optically pumped long wavelength laser configured to provide a long wavelength laser output, the long wavelength laser optically pumped by the short wavelength laser output;
- and
- a removable optical subassembly including the prefabricated long wavelength laser and located within the housing in a position at which the output of the short wavelength laser is applied to the long wavelength laser.
A method for forming an optical assembly, comprising the steps of:
- locating a prefabricated electrically pumped short wavelength laser in a housing;
- locating a long wavelength optically pumped laser in a removable optical subassembly;
- and
- placing the removable optical subassembly containing the long wavelength laser in the housing and in a light output path of the short wavelength laser, such that an output of the short wavelength laser is directed into the optical subassembly and optically pumps the long wavelength laser resulting in a long wavelength laser output.
A long wavelength laser, comprising:
- a housing;
- a prefabricated electrically pumped short wavelength laser located in the housing and having a short wavelength laser output;
- and
- a removable optical subassembly containing a prefabricated optically pumped long wavelength laser, the removable optical subassembly located in the housing and in a path of the short wavelength laser output so that the short wavelength laser output optically pumps the long wavelength laser.
