The influence of several vital parameters ( the linewidth enhancement factor or , reflectivities of the facet adjacent to the external cavity r and the external reflector r ) of the ecld on the bistable characteristics have been discussed briefly 并初步介绍了ecld几个关键参量,谱线展宽因子和ld镀膜端面反射率r对双稳环基本特性的影响。
It is shown that the pump parameter and intensity noise correlation time are the major factors of the first - order - like transition . angular noise correlation time has great influence on the linewidth in the power spectrum 研究结果表明,抽运参量和噪声相关时间是激光系统出现一级相变类比的关键因素,角噪声相关时间对强度谱分布中的线宽影响较大。
The grating and reticle , which linewidth errors are less than 10 % nominal linewidth , are fabricated by ldw . for the first time metallic mesh film with area 200mm 200mm fabricated by using ldw photolithography and coating technology 本文完成了直角坐标激光直写光刻技术研究,开展了离焦激光直写光刻的工艺研究,制作了光栅和网格分划板,线宽误差控制在10 %以内。
This result is not in contradiction to the case of electromagnetically induced transparency where coupling field linewidth gives rise to or increases absorption , and linewidth is still suppresses the coherence of system 虽然在两种情况下,发生的现象完全不同,但是线宽的这两种效应是一致的,即线宽的两种不同作用都是导致退相干,并非简单地认为线宽总是引进或者增强吸收。
In sections , we reduced the linewidth of parametric light considerably by use of the elements such as prisms and gratings or by etalons . we can obtain the linewidth less 2nm , less o . snm , less 0 . 06nm , respectively 第三章根据clbo - opo输出线宽较大的特点,理论上分析采用棱镜、光栅、标准具等线宽压窄元件来压窄输出参量光线宽,分别获得了小于ztun 、 0 . snm 、 0 . 06nm的输出线宽。
