摘要	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.
其他摘要	一种光纤激光装置，包括能够发射源激光束的激光源，配置成接收源激光束的双折射光束分离器，以及将源激光束分成具有相互正交偏振的o射线和e射线，以及保偏光纤，包括以纤芯直径为特征的纤芯，其中在射线和e射线出射双折射光束分离器之后，o射线和e射线分开的距离大于偏振保持的纤芯。纤维。保偏光纤定位成将射线和射线中的一个耦合到光纤纤芯中。射线和射线之一透过偏振保持光纤以形成输出激光束。
