Abstract
A laser apparatus having multiple laser devices coupled together. The laser devices comprise optical fibers with laser active regions. Each of the fibers has a reflector disposed at one end and is connected to a combiner on the other end. A laser pump device for each fiber provides pump energy to the laser active regions. Light propagating in the fibers interacts so as to form inphase states. The array of fibers may be coupled either in pairs or altogether between the reflector and the laser active region.
Claims8
A method of coherently combining multiple laser oscillators, the method comprising:
- providing a plurality of laser oscillators operating in different frequency ranges wherein each laser oscillator in the plurality of laser oscillators oscillates light between a first reflector and a second reflector;
- coupling the plurality of laser oscillators between the first reflector and second reflector;
- mutually adjusting, through said coupling, said different frequency ranges wherein the plurality of laser oscillators operate in the same frequency range upon said adjusting.
An apparatus comprising:
- a plurality of laser oscillators operating at different frequency ranges, wherein each laser oscillator in the plurality of laser oscillators oscillates light between a first reflector and a second reflector;
- a combiner coupling the plurality of laser oscillators between the first reflector and second reflector and adjusting the plurality of laser oscillators to operate in the same frequency range.
