Advances in High Power Optical Fiber Lasers. Phase 1

Abstract

We have proposed and carried out a series of experiments that could be of significance to the development of high power cladding pumped optical fiber lasers. First, at low power, we have shown how a more complex cavity can result in increased power by combining fiber lasers using a truncated 2x2 coupler. We believe that this can lead to the concatenation of many couplers while still using the more convenient technique of end pumping. Experiments are in progress to investigate this concept further. Finally, we propose a technique, that has been demonstrated by others in Nd bulk glass, for increasing the ionic concentration of ytterbium and erbium in fiber lasers and still avoid problems associated with concentration quenching.
