In such dense wavelength division multiplexing ( dwdm ) systems a light source having narrower linewidth and further stability of the wavelength has become a requirement 在这样的密集波分复用( dwdm )系统中,光发送机的工作波长必须稳定,线宽必须窄,以避免复用信道间信号相互窜扰。
This paper introduces the development of fiber - optic mach - zehnder interferometer during measuring linewidth parameter of single - frequency lasers , and the experiment result has been given 摘要介绍了作者在测量单纵模激光器线宽参数的过程中,研制的马赫曾德尔光纤干涉仪,并给出了实验结果。
In addition , the temporal evolution of detailed spectral feature ( such as linewidth and line shape ) can provide important information about ablation dynamics and perhaps target compression in laser - fusion studies 精细光谱特色的时间分辨(如线宽,线形)还可提供靶压缩等动态过程中的信息。
In order to realize a experiment of laser cooling and trapping atoms , we have set up a laser diode injection locking system and achieved a laser with single mode , narrow linewidth and 60mw power output 为了进行原子冷却与俘获的实验研究,我们用注入锁定的方法获得了约60mw的单模窄线宽激光输出。
The influences of longitudinal phonon and transverse phonon on the softening and broadening in the magnon linewidth are compared , and the influences of the parameters are also illustrated 比较了纵向声子与横向声子对磁振子谱的软化与磁振子谱线增宽的影响,也讨论了各项参数的变化对磁振子谱的软化与磁振子谱线增宽的影响。
