We experimentally establish a non-classical correlation between a single Stokes photon and the collective spin excited state of a cold atomic ensemble by using a spontaneous Raman scattering process. The correlation between them can be proved by transferr
A novel numerical algorithm is proposed to reconstruct the Laplacian of an object field from one single in-line hologram. This method uses two different reconstruction distances of z and z \Delta z, or two different reconstruction wavelengths of \lambda

We study a Zeeman slower using the magnetic field generated by a pair of coils for a magneto-optical trap. The efficiency of the Zeeman slower is shown to be dependent on the intensity and frequency detuning of the laser light for slowing the atoms. With
We experimentally demonstrate the generation of highly coherent Type-II micro-combs based on a micro-resonator nested in a fiber cavity loop, known as the filter-driven four wave mixing (FD-FWM) laser scheme. In this system, the frequency spacing of the c
Ta2O5/SiO2 dielectric mirrors deposited by ion beam sputtering (IBS) are studied. The multi-shot laser-induced damage threshold (LIDT) and its dependence on the number of shots are investigated, after which we find that the multi-shot LIDT is lower than t
在椭圆偏振仪测量原理的基础上,采用Forouhi-Bloomer模型的参数匹配模型,分析非晶硅的物理性质,利用温度与禁带宽度间的关系,得到利用椭圆偏振仪测试非晶硅薄膜热光系数的方法与非晶硅热光系数的表达式,利用相关文献对其进行验证,验证结果表明,该方法是可行的。
美帝海军正与李尔·西格勒公司交涉,请其研制一种新的舰用激光雷达。该种装置将提供一种可靠的、非常精确的方法。使能在密集队形或战斗状态下进行工作。与微波雷达不同,这种激光装置在非常近距离下的测量分辨率特别高。

相比于传统同步并行计算策略,在异步并行计算框架下,针对最常用的总变分(TV)最小化重建模型,通过将其转化为不动点迭代问题,并利用异步交替方向法(ADM)进行求解,推导出基于TV最小化模型的异步ADM迭代重建算法,即异步交替方向总变分最小化算法(Async-ADTVM)。利用消息传递接口技术将该算法在图形处理器(GPU)集群上进行测试,进一步提高了原始基于TV最小化模型的迭代重建算法的计算效率。实验
