光栅拼接法是目前制作大尺寸平面衍射光栅的重要方法之一，而拼接误差是评价拼接光栅是否能够使用的重要指标之一。实时定量测量拼接误差，能够实现对拼接误差的自动闭环调整，通过实时指导拼接提高光栅拼接的精度。建立了衍射波前与光栅拼接误差关系的数学模型，分析了干涉仪测量光栅拼接误差的原理，用ZYGO干涉仪实现拼接光栅0级及-1级衍射波前的数字化定量提取，分析并计算了拼接误差波前，得到五维拼接误差的数值解。利用拼接光栅-2级的衍射波前验证五维拼接误差结果的准确性，实验结果表明由0级、-1级、-2级拼接波前计算的拼接误差
Excess frequency noise induced by mechanical vibration is the dominant noise source at low Fourier frequencies in fiber-delay-line stabilized lasers. To resolve this problem, a double-winding fiber spool is designed and implemented that has ultralow accel
We present a novel and simple method to obtain an ultrawide free spectral range (FSR) silicon ring resonator together with a tuning range covering the entire spectrum from 1500 to 1600 nm. A ring resonator with a large FSR together with a high Q factor, h
本文用矩阵分析方法讨论了任意时间场分布的光脉冲在一般色散介质中的传输,引入了光脉冲质量因子M2τ和一般化的脉冲复参数P-1,得到了具有任意形状和任意啁啾的光脉冲在色散光学系统中传输的ABCD定律。
The wind error of multichannel lidar system is simulated through calculation of atmospheric back-sacttering echo signal and weighted least-square fitting. By comparing the wind errors of four wavelengths of the Nd:YAG laser, two kinds of phenomena are fou
Stray light in high-power laser facilities not only decreases the gain capacity of the main amplifier, but can also cause permanent damage to optical components, greatly threatening the safety operation of the SG-III. This Letter reports a technique for q
We focus on a more difficult kind of beam splitter in a cemented cube. The specification is that when the incident angle is 45°, the reflectivity in the visible range is 70%±2%, and the reflectivity at 1570 nm is not less than 90%. The film is thick, so c
Miniature optical fiber sensors with thin films as sensitive elements could open new fields for optical fiber sensor applications. Thin films work as sensitive elements and a transducer to get response and feedback from environments, in which optical fibe
测量了Cr4 :YAG、Cr4 :Mg2SiO4晶体在室温和液氮温度下的荧光光谱、吸收光谱和激发态寿命,讨论了温度变化时,两种晶体中Cr4 近红外辐射积分强度变化与激发态寿命变化的关系,得出结论:在77～300 K范围内,Cr4 的3T2能级荧光辐射截面本身受温度影响不大,Cr4 辐射荧光的变化,主要是由无辐射驰豫速率随温度变化而引起的。
Liquid 4,7-bis(1-decynl)-2,1,3-benzothiadiazole (DOBT) is found to exhibit good photoluminescence (PL) with high PL efficiency up to 17.8%. In particular, DOBT shows electron mobility of 5.2×10-6 cm2V-1s-1, demonstrating a promising n-type liquid semicond
