Claims
- 1. Optical amplifier apparatus comprising
- at least one section of fiber which exhibits gain when excited by an optical pump signal,
- multiple pump lasers for generating said pump signal as a combination of a plurality of pump signals from said multiple lasers, and
- a coupler for coupling said pump signals to said at least one gain section, CHARACTERIZED IN THAT
- said pump lasers have at least partially overlapping resonators, and
- said at least one gain section is located external to said resonators.
- 2. The apparatus of claim 1 further characterized in that said coupler is located at least partially within said resonators.
- 3. The apparatus of claim 1 comprising a plurality of said gain sections located external to said resonators and wherein said pump signal is delivered to each of said sections.
- 4. The apparatus of claim 2 wherein said sections are arranged in tandem with one another.
- 5. The apparatus of claim 1 wherein said pump lasers comprise diode lasers.
- 6. An optical amplifier apparatus comprising
- at least one section of fiber which exhibits gain when excited by an optical pump signal,
- multiple pump lasers for generating such pump signal as a combination of a plurality of pump signals from said multiple lasers, and
- a coupler for coupling said pump signals to said at least one gain section, CHARACTERIZED IN THAT
- said pump lasers have at least partially overlapping resonators, and
- said coupler is located at least partially within said resonators.
- 7. The apparatus of claim 6 comprising a plurality of said gain sections located external to said resonators and wherein said pump signal is delivered to each of said sections.
- 8. The apparatus of claim 7 wherein said sections are arranged in tandem with one another.
- 9. The apparatus of claim 6 wherein said pump lasers comprise diode lasers.
