光纤激光器具有转换效率高、光束质量好、结构紧凑、维护方便等优点,在科学研究、工业加工、国防军事等领域具有广泛的应用前景。超荧光(放大的自发辐射,ASE)光源具有光谱覆盖范围宽、时间相干性低、温度稳定性好等特点,在光学层析成像(OCT)、高精度光纤陀螺传感、单光子产生等方面具有广泛应用。此外,超荧光与激光相比,还具有无弛豫振荡、无模式竞争、极高时域稳定性等突出特点。而基于掺杂光纤搭建高功率的超荧光光纤光源(SFS),有望成为新型高亮度光源的技术方案。 Fiber lasers have the advantages of high conversion efficiency, good beam quality, compact structure and convenient maintenance. They have wide application prospect in the fields of scientific research, industrial processing, national defense and military fields. Superfluorescent (amplified spontaneous emission, ASE) light sources have the characteristics of wide spectral coverage, low temporal coherence and good temperature stability. They are widely used in optical tomography (OCT), high-precision fiber optic gyro sensing and single photon generation Has a wide range of applications. In addition, super-fluorescence compared with the laser, but also has no relaxation oscillation, modeless competition, high stability and other prominent characteristics of the time domain. And based on doped fiber to build high-power super-fluorescence fiber light source (SFS), is expected to become a new type of high-brightness light source technology program.
