多波长光纤激光器由椭圆芯掺铒光纤作为各向异性增益介质构成。宽带光纤反射器和萨尼亚克环反射器形成法布里-珀罗谐振腔。获得了三个激光波长，它们在室温下稳定超过一个小时。以其中一个作为参考波长，我们可以通过偏振控制器切换另外两个。激光波长也是可调的。还探讨了掺铒光纤各向异性增益行为的影响。
A multiwavelength fiber laser is constructed with an elliptical core erbium-doped fiber serving as an anisotropic gain medium. A broadband fiber reflector and a Sagnac loop reflector form a Fabry-Perot resonant cavity. Three lasing wavelengths are obtained which are stable over an hour at room temperatures. With one of them as reference wavelength, we can switch the other two by a polarization controller. The lasing wavelengths are also tunable. The effects of the anisotropic gain behavior of the erbium-doped fiber are also explored.
