基于全量子理论,分别研究了几种重要的光场作用下,从原子玻色-爱因斯坦凝聚(BEC)体耦合输出的原子激光的量子相干特性。结果表明,粒子数态光场诱导的原子激光总是反聚束的,相干态光场诱导的原子激光是任意阶相干的,而压缩相干态光场诱导的原子激光总是聚束的。表明用光场诱导产生的原子激光具有与初始光场完全相同的量子相干性质。

建立了基于光线跟踪算法的大气延迟校正模型和表面压力模型,利用美国国家环境预报中心提供的大气数据作为这两个模型的大气参数,将不同的大气参数代入模型进行星载激光测高仪大气延迟校正的数值模拟。模拟结果表明,天顶方向的大气延迟校正值约为2.30m。通过模拟分析大气延迟效应对温度、大气可降水、测站点高度及高度角等敏感因子的敏感性,认为大气延迟效应对温度、大气可降水的敏感性较弱,对卫星高度角及测站点高度的敏感
We propose a plasmonic sensor with variable refractive index (RI), which exhibits high sensitivity and extraordinary optical transmission (EOT). Its variable RI is attributed to its dielectric layers and metallic slit arrays. According to simulation resul
We present an experimental setup capable of time-resolved photoluminescence spectroscopy for photon energies in the range of 0.51 to 0.56 eV with an instrument time response of 75 ps. The detection system is based on optical parametric three-wave mixing,

We demonstrate that the filamentation process is strongly influenced by the polarization state of the driver laser. When the laser polarization changes from linear to circular, the critical power for the self-focusing of a Ti:Sapphire laser (800 nm, 40 fs
