Abstract:
1. A diode pump comprising: a single diode emitter emitting a single multi-mode beam, the multi-mode beam comprising a plurality of discrete wavelengths and having a beam size; a portioning element configured to portion the multi-mode beam into a plurality of partitions, each partition comprising only one of the wavelengths of the multi-mode beam and having a partition size smaller than the beam size, the beam size substantially equaling a sum of the partition sizes; a combining element configured to receive and converge each partition onto a dispersive element, wherein the dispersive element transmits the converged partitions; and a partially-reflective output coupler arranged to receive the converged partitions from the dispersive element, to reflect a portion of the converged partitions toward the dispersive element, and to transmit an output beam having (i) the plurality of wavelengths and (ii) a size substantially equal to one of the partition sizes.
