摘要	A superfluorescent broadband fiber laser source comprises a fiber doped with laser material coupled to a multiplexing coupler. In the preferred embodiment, a source of pumping illumination provides pumping light to the doped fiber, and the coupler is adjusted to have a 0% coupling efficiency at the wavelength of the source. The pumping light is sufficiently intense to produce amplified spontaneous emission within the doped fiber, and gives rise to a forward signal and a backward signal. One of the superfluorescent signals is reflected back to the doped fiber by a reflector cemented to one end of the doped fiber or to one end of another fiber through the coupling function of the coupler. The coupler is adjusted to provide complete coupling at the frequency of the lasing light. The temperature dependence of the coupler can be selected to reduce or cancel the temperature dependence of the superfluorescent signal. Other arrangements utilizing the multiplexing properties of the coupler are also described. An all-fiber reflector can also be used.
其他摘要	超荧光宽带光纤激光源包括掺杂有耦合到多路复用耦合器的激光材料的光纤。在优选实施例中，泵浦照明源为掺杂光纤提供泵浦光，并且调节耦合器以在光源波长处具有0％耦合效率。泵浦光足够强以在掺杂光纤内产生放大的自发发射，并产生前向信号和后向信号。其中一个超荧光信号通过耦合器粘合到掺杂光纤的一端或通过耦合器的耦合功能反射回掺杂光纤。调节耦合器以在激光的频率下提供完全耦合。可以选择耦合器的温度依赖性以减少或消除超荧光信号的温度依赖性。还描述了利用耦合器的多路复用特性的其他布置。也可以使用全光纤反射器。
