Abstract
A fiber laser device includes a laser source that can emit a source laser beam, a birefringent beam separator configured to receive the source laser beam and to split the source laser beam into an o ray and an e ray which have mutually orthogonal polarizations, and a polarization maintaining fiber comprising a fiber core characterized by a core diameter, wherein after the o ray and the e ray exit birefringent beam separator, the o ray and the e ray are separated by a distance that is larger than the fiber core of the polarization maintaining fiber. The polarization maintaining fiber is positioned to couple one of the o ray and the e ray into the fiber core. The one of the o ray and the e ray transmits through the polarization maintaining fiber to form an output laser beam.
