Abstract: The modularized fiber optic laser system includes at least one master oscillator for producing a master laser signal and a plurality of optical amplification modules that independently amplify portions of the master laser signal. Each optical amplification module includes a plurality of optical fiber amplifiers and at least one pump source associated with each optical fiber amplifier for pumping the respective optical fiber amplifier. The optical amplification module also includes a power source for providing power to the pump sources. Each optical amplification module preferably consumes no more than a first predetermined amount of power during operation. As such, the power source is adapted to provide at least a first predetermined amount of power without recharging and without power generation. Each optical amplification module is also designed to produce no more than a first predetermined amount of heat during operation.

Abstract: An incoherent fiber optic laser system is provided which provides a high quality output beam which is readily scalable and which can be focused to a target location located relatively near or relatively far without requiring sophisticated optical elements. The incoherent fiber optic laser system includes a plurality of single mode laser sources, such as a plurality of fiber optic amplifiers, for providing single mode laser signals. The laser sources, such as the fiber optic amplifiers, operate incoherently with respect to one another such that the resulting laser signals are also incoherent. The incoherent fiber optic laser system also generally includes a plurality of single mode optical fibers for routing the incoherent laser signals as desired. In addition, the incoherent fiber optic laser system can include a plurality of lenses for collimating the incoherent laser signals provided by respective ones of the single mode optical fibers.
