Abstract
An optical pump may include a polarization element to separate pump light into a first component beam and a second component beam, wherein the polarization element is to separate the pump light such that the first component beam has a first polarization and the second component beam has a second polarization that is different from the first polarization. The optical pump may include a gain medium to absorb a portion of the first component beam and a portion of the second component beam, and transmit an unabsorbed portion of the first component beam and an unabsorbed portion of the second component beam. The optical pump may include one or more optical elements to at least partially isolate a pump source from the unabsorbed portion of the first component beam and the unabsorbed portion of the second component beam.
