矩形内包层掺Yb^(3+)石英光纤的研制及其抽运性能

Fabrication of Yb^(3+) Doped Silica Fiber with Rectangular Inner Cladding and Its Pumping Performance

利用改进的化学汽相沉积工艺加溶液掺杂法 ,配合光学加工技术 ,自行设计并研制出内包层为矩形等新颖结构的掺Yb3 +双包层石英光纤 ,实现了上述光纤的包层抽运激光器的成功运转。矩形光纤在 10 75 6nm波长处获得 84mW的最大激光输出功率 ,斜率效率达 77%。

The Yb3+-doped double-clad silica fibers with rectangular and other novel inner-cladding have been made by using modified chemical vapor deposition process, solution-doping and optical machining altogether. The operation of these cladding pumped fiber lasers is demonstrated. The maximal laser output of rectangular fiber laser is 84 mW at the wavelength 1075.6 nm, and a slope efficiency of 77% has been achieved.
