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.
