Abstract

An all-fiber 1.48-mum generator based on a laser-diode-pumped Yb-doped double-clad laser and a cascaded Raman wavelength converter has been developed. Second-order Raman Stokes radiation was generated in a phosphosilicate-fiber resonator formed by two pairs of Bragg gratings. A slope efficiency of the Raman converter of 48% with respect to the power emitted by the double-clad Yb laser has been achieved. We obtained an output power of 1 W at a slope efficiency of 34% with respect to the laser-diode array power, with a total optical-to-optical efficiency of 23%.

摘要

一种基于激光二极管泵浦掺镱双包层激光器和级联拉曼波长转换器的全光纤1.48微米发生器已被研制出来。二阶拉曼斯托克斯辐射是在由两对布拉格光栅形成的磷硅光纤谐振器中产生的。相对于双包层镱激光器发射的功率，拉曼转换器的斜率效率达到了48%。相对于激光二极管阵列功率，我们获得了1瓦的输出功率，斜率效率为34%，总光光效率为23%。
