1. Apparatus for providing optical radiation, comprising:
a pump array configured to provide pump radiation;
a first pump combiner, comprising a coupling means and a pump waveguide disposed between the pump array and the coupling means;
a plurality of waveguides, each waveguide comprising a pump guide for guiding the pump radiation, and a gain medium which
emits the optical radiation when it is pumped by the pump radiation;
a transmission cable disposed between the coupling means and the waveguides; and
an optical switch for routing the pump radiation to different ones of the waveguides.
