【摘要】 采用一种新的连接方式使一段掺Yb3 + 光纤处于未抽运位置。以这段掺Yb3 + 光纤作为对信号光的吸收体 ,利用它在驻波场中的可饱和吸收作用 ,再结合带通滤波器 ,在掺Yb光纤激光器中获得了波长 10 5 4 5 6nm ,3dB带宽小于 0 0 7nm的窄线宽激光输出。对未抽运掺杂光纤吸收体在掺Yb3+ 窄线宽光纤激光器中的作用进行了较为详细的研究更多还原

【Abstract】 A new connecting way was done in Yb 3+ doped fiber laser, in which a Yb 3+ doped fiber was located at an unpumped place. Narrow linewidth lasing was obtained by using of a bandpass filter and the unpumped Yb 3+ doped fiber acted as saturable absorber. The linewidth of output laser was less than 0.07 nm. The effect of unpumped dopant fiber saturable absorber in Yb 3+ doped narrow linewidth fiber laser was researched in detail.更多还原
