Apparatus for providing optical radiation

摘要

Apparatus for providing optical radiation ( 10 ) comprising a pump array ( 8 ) for providing pump radiation ( 7 ), a first pump combiner ( 1 ), and a waveguide ( 3 ), wherein the pump radiation ( 7 ) from the pump array ( 8 ) is coupled into the waveguide ( 3 ) via the first pump combiner ( 1 ), and wherein the waveguide ( 3 ) comprises a pump guide ( 4 ) for guiding the pump radiation ( 7 ), and a gain medium ( 5 ) which emits the optical radiation ( 10 ) when it is pumped by the pump radiation ( 7 ).
