单泵浦超连续光纤激光器的研究

超连续光纤光源是近年来光通信领域最重要的研究成果之一,也是最近几年得到国内外广泛研究的一种新型多波长光源。这种光源在常温下可以得到稳定的多波长输出,并具有噪声低、带宽范围大、性能稳定、易于控制等优点,成为密集波分复用(DWDM)系统的多波长光源研究中的热点。本文介绍了多波长超连续光纤光源中涉及到的各种器件的原理和功能。详细描述了整个实验过程,通过对各个部件的选择,对各个环节的调节测试,以及几次方案的修改,最终将多波长光源调到比较好的效果。实现了频谱的展宽和多波长的输出,稳定和功率是制约这个实验结果的主要原因。

Study of Supercontinuum Laser Source by Single Bump

Supercontinuum source is one of the most important results in the fiber-optic communications recent.It is also a kind of new source which is researched mostly in the world.This kind of source can get steady multiwavelength in the normal temperature,and have lot of excellence such as low noise,large bandwidth,steady and easily control.It is the most important thing in the research of the multiwavelength source used in DWDM system.The first part of this article show some basic principle and function of the instrument used in the multiwavelength supercontinuum laser.We describe particularly the process of experimentation particular: the choice of the experimentation instrument;the modulation and testing all kind of instrument and development of the project.At last we get the better laser pulse based on this source,carry out extending of the pulse bandwidth and multiwavelength.We get the result of that the most important factor of this experimentation is the steady and high power laser pulse.
