本文报道由1.06μm YAG:Nd~(3 )激光引起的LiNbO3光折变效应.测量了LiNbO3双折射率变化的空间分布,并用Twyman-Green干涉仪进一步证实折射率变化的空间分布是不对称的.此外,还测量了光折变与退火温度和时间相关的曲线.证实了Δn0~(3~4)Δn.

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 theoretically investigate the delay-dependent attosecond transient absorption spectra in the helium atom dressed by an infrared laser pulse in the wavelength range of 800–2400 nm. By numerically solving the three-dimensional time-dependent Schr dinger

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
