摘要： A semiconductor pump laser uses a depolarzer to depolarize the pump light entering the fiber amplifier. The depolarized light source is useful for reducing polarization dependent gain of fiber amplifiers. The pump laser includes one or more semiconductor, coherence-collapsed laser sources emitting polarized pump outputs, and one or more depolarizers disposed to depolarize the polarized pump output from the lasers. One or more fiber outputs are coupled to the one or more depolarizers to receive depolarized pump light. The depolarizer may include an N×M polarization preserving coupler having N inputs and M outputs, N and M being at least 2, an input to the depolarizer at a first coupler input, an output port from the depolarizer at a first coupler output. A polarization-controlling optical path is coupled between a second coupler output and a second coupler input. A polarization of light exiting the N×M coupler through the second coupler output is substantially orthogonal to a polarization of light entering the N×M coupler through the second coupler input.

摘要： Optical pumping arrangements are provided for the broadband or multiple wavelength pumping of optical sources. Sources may be based on Raman gain media and may use multiple output couplers to couple out different wavelength ranges. Cascaded Raman resonator (CRR) configurations may also be used. Overlapping resonators at different wavelengths may be configured to share gain media, and may have separate portions in separate optical paths. Attenuation filters may also be used that are matched to the gain profile of a gain medium, to flatten the gain spectrum and allow equalization of gain to different output wavelengths. In one embodiment, polarization maintaining fiber is used to develop resonant conditions at different wavelengths in different polarization states. Wideband output gratings may be substituted for narrowband gratings to provide CRR configurations with a broader output band. Broadband amplification may also be provided by using a laser source operating in coherence collapse. The multiple wavelength pumping lends itself to a pumping arrangement in which sources at different wavelengths are combined into separate transmission/gain media such as the different fibers of an optical fiber cable.
摘要翻译：提供了用于光源的宽波长或多波长泵浦的光泵浦装置。源可以基于拉曼增益介质，并且可以使用多个输出耦合器耦合出不同的波长范围。也可以使用级联拉曼谐振器（CRR）。可以将不同波长的重叠谐振器配置成共享增益介质，并且可以在单独的光路中具有分离的部分。还可以使用与增益介质的增益曲线匹配的衰减滤波器，以平坦化增益谱，并允许将增益均衡到不同的输出波长。在一个实施例中，使用偏振保持光纤来发展不同偏振态的不同波长的谐振条件。宽带输出光栅可以代替窄带光栅，以提供具有更宽输出频带的CRR配置。也可以通过使用在相干塌陷中操作的激光源来提供宽带放大。多波长泵浦本身适用于泵送装置，其中将不同波长的源组合成单独的传输/增益介质，例如光纤电缆的不同光纤。
