摘要
The laser and amplifiers based on RE-doped fiber have been paid much attention to. Recently, fiber superfluorescence- the amplified spontaneous emission (ASE)began to receive more interest. As a broadband source, the superfluorescence is needed in many fiber sensor applications, in particular the fiber gyroscopes and some signal-processing fiber systems. Owing to the high gain in RE-doped fiber, significant superfluorescence power
