In this Letter, we numerically simulate the generation of a 1–15 μm mid-infrared supercontinuum (SC) from a highly nonlinear Ge11.5As24Se64.5-based photonic crystal fiber (PCF). This ultra-broadband SC is achieved in a 100 mm long PCF pumped using 85 fs laser pulses operated at 3.1 μm and a peak pulse power of 3 kW. The proposed design offers a flat dispersion profile with two zero dispersion wavelengths. This broad and flat dispersion profile of the Ge11.5As24Se64.5 PCF, combined with the high nonlinearity (2474 W 1 km 1), generates an ultra-broadband SC.

带输运模型是目前被广泛接受的光折变理论.该模型以扩散机制为主.在某些情况下加上两个修正,即有外场时的漂移机制和光生伏打效应.其中光生伏打效应被考虑为等效于外加电场.而且常常被忽略了.作者认为光生伏打效应应当总被看作与扩散相并列的光折变机制,而且在铁电晶体.如LiNbO_3.中.光生伏打效应常常超过扩散而成为光折变过程的主要机制.文中将已有的光生伏打效应的唯像理论加以扩展,对产生光折变光栅的过程给出了较全面的分析.
Tunable optical delay lines are one of the key building blocks in optical communication and microwave systems. In this work, tunable optical delay lines based on integrated grating-assisted contradirectional couplers are proposed and experimentally demons

The theory of speckle formation in laser scanning display system is established based on the averaging effect of eye response as laser beam scanning through an eye resolution spot. It is analyzed that speckle reduction can be obtained by averaging states
No instrument is able to measure directly the quantum entanglement of a system. However, both theory and experiment, following the well-known Bell inequality, reveal the existence of the entanglement phenomenon in quantum mechanics. To examine the charact
研究了激光与物质相互作用中激光输出不稳定性对材料中温度场分布的影响以及减少这种影响的途径。 首次在激光热传导方程中引入噪声项, 推导了噪声影响下该激光热传导方程的解。 研究发现, 温度场的分布受噪声的影响, 材料表面温度的涨落较大, 而材料的深处涨落较小; 温度场的涨落还和激光加热的过程有关, 随激光加热时间的增长, 温度场的涨落增大。 此外, 材料的热传导系数、 热扩散率和发射率均对温度场的涨落有影响。 文中还提出了减小激光输出不稳定性影响的几条途径。
研究了碱金属氟化物对掺Yb3 氟磷玻璃的光谱性质和析晶稳定性能的影响。运用倒易法计算了Yb3 的发射截面。结果显示, LiF的引入对吸收和发射截面的提高作用较大并出现最佳引入量极值, 其次为KF。碱金属氟化物的引入可提高二元体系的析晶稳定性能,使玻璃网络结构得到改善; 拉曼光谱显示二元体系中引入YbF3后玻璃网络结构得到增强, 而在引入碱金属氟化物的三元体系中掺杂YbF3后破坏了网络完整性,降低系统析晶稳定性能。
对含光源等过亮区域场景的自动对焦较为常见,这些区域导致了图像像素的饱和,然而所提出的现有的评价函数适用于一般场景,无法适用于像夜景光源的场景。针对这一问题,通过分析饱和像素在离焦过程中的特性,提出了一种去除饱和像素的图像清晰度评价方法,且其可以用于评估包含光源或者过亮区域场景的图像质量。通过对大津法进行修改得到对焦窗口二值图,并利用形态学膨胀手段扩展饱和像素区域,以防止其在离焦过程中产生弥散,得到
