Abstract:
1. A system configured to transform an input optical beam having an input wavelength, an input brightness, and an input optical power into an output optical beam, the output optical beam having an output wavelength distinct from the input wavelength, the system comprising: an optical power device configured to provide the input optical beam; an output fiber device including an output fiber, the output fiber device configured to transform a pump optical signal having an intermediate wavelength into the output optical signal, the output fiber having a cross-sectional area value A a set of input fiber devices configured to receive the input optical beam and to generate a pump optical beam therefrom, the input fiber devices including respective input fibers having respective first cross-sectional areas A a tapered fiber bundle including a set of bundled fibers at a near end and an output at a distal end, the near end of the tapered fiber bundle configured to collect the pump optical beam from the input fibers and to provide the pump optical signal to the output fiber, each fiber k in the set of bundled fibers: a cross-sectional area of the output of the tapered fiber bundle having a cross-sectional area value A
