基于菲涅耳衍射理论分析了畴腐蚀二维周期结构掺镁铌酸锂晶体光分束器的泰伯效应，对光分束器不同占空比D及泰伯分数β条件下的近场光衍射自成像进行了数值模拟研究。设计并制备了不同占空比的畴腐蚀掺镁铌酸锂晶体光分束器，并对其进行了分数泰伯光衍射自成像的实验研究，得到了不同泰伯分数β条件下的近场光衍射强度分布。结果表明，当光分束器占空比D=52%、泰伯分数β=2时，近场衍射自成像效果最佳，实验结果与理论研究结果相符。
High-power fiber lasers have experienced a dramatic development over the last decade. Further increasing the output power needs an upscaling of the fiber mode area, while maintaining a single-mode output. Here, we propose an all-solid anti-resonant fiber
聚焦激光脉宽和偏振对飞秒光丝诱导燃烧场中间产物荧光光谱的影响,通过改变激光脉宽、偏振状态,观测了燃烧中间产物如OH、CH、CN、C2分子和C原子的荧光光谱变化。结果发现:随着激光脉宽和偏振椭圆率增大,各组分荧光信号强度减小,这是因为光丝内激光钳制强度及等离子的密度与激光脉宽、偏振密切相关,进而导致多光子激发燃烧中间产物的信号随之变化。

The application of laser pulses with psec or shorter duration enables nonthermal efficient ultrahigh acceleration of plasma blocks with homogeneous high ion energies exceeding ion current densities of 1012 A cm??2. The effects of ultrahigh acceleration of
Quantitative interferometric microscopy is an important method for observing biological samples such as cells and tissues. As a key step in phase recovery, a fast phase unwrapping algorithm is proposed. By shifting mod 2\pi wrapped phase map for one pixe
给出了用LS-3二极管激光光谱仪记录的SF_(6v_2 v_4)合频带的高分辨光谱,观察到重球陀螺分子核运动角动量改变的跃迁。
In order to achieve small size, light weight, and immunity to electromagnetic interference, it is desirable to replace bulky coaxial cables with optical fiber in advanced radar front-ends. Such applications require a large dynamic range that is beyond the
Yb-Er codoped Na2O-Al2O3-P2O5-xSiO2 glasses containing 0-20 mol% SiO2 were prepared successfully. The addition of SiO2 to the phosphate glass not only lengthens the bond between P^{5 } and non-bridging oxygen but also reduces the number of P=O bond. In co
