双二色镜腔的国产掺Yb^(3+)双包层光纤激光器

Two-dichroic-mirror Cavity Yb^(3+)-doped Double-clad Fiber Laser

国产双包层光纤对泵浦光不能实现有效吸收,从而导致剩余泵光过多的现象,本文采用了双二色镜的腔结构,研究了国产D型内包层掺Yb3+双包层光纤激光器的输出特性,得到了无剩余泵光的激光脉冲输出,中心波长为1．076μm,平均功率为604 nw．

A linear cavity double-clad fiber laser basing on two-dichroic-mirror, which can reuse the residual pump light existing in the output laser effectively, is presented. The output characteristics of D-shape inner cladding Yb^3＋-doped double-clad fiber laser are experimentally studied. The laser wavelength is 1. 076μm, and the average power of the pulse output without pump light is 604 roW.
