Abstract
Optical pumping arrangements are provided for the broadband or multiple wavelength pumping of optical sources. Sources may be based on Raman gain media for amplification. Broadband amplification is provided by using a laser source operating in coherence collapse. Such a source may make use of an optical generator and an output coupler which are sufficiently far apart from one another as to ensure coherence collapse.
Claims22
An optical amplifier comprising:
- an optical gain medium capable of generating optical gain via stimulated Raman scattering;
- and
- an optical pump source comprising a laser source operating in coherence collapse mode.
An optical amplifier comprising:
- an optical gain medium capable of generating optical gain via stimulated Raman scattering;
- and
- an optical pump source comprising a laser source operating in coherence collapse mode, the laser source including an optical generator, a first cavity reflector and a partially reflective output coupler reflector, wherein an optical resonance condition is established between the first cavity reflector and the output coupler reflector.
A method of amplifying an optical signal, the method comprising:
- providing an optical gain medium capable of generating optical gain via stimulated Raman scattering;
- and
- pumping the gain medium with an optical pump source comprising a laser source operating in coherence collapse mode.
