全光扫描装置设计及实验研究
Design and experimental research of alloptical scanning device
摘要
针对惯性约束聚变研究中高时间分辨测量的需求,详细分析并设计了一种新型的高时间分辨的全光扫描装置。该装置根据光生载流子效应、波导传输和棱镜色散原理,采用全光学元件,实现了全光器件的类条纹相机扫描功能。设计制作了具有棱镜结构和光偏转功能的全光扫描模块。以1053 nm激光为传输光,527 nm激光为泵浦光,完成了脉宽为8 ps的脉冲激光信号作用下的光偏转实验。从技术上验证了全光扫描技术的可行性。
Abstract
For more precise measurements of the temporal evolution of plasma in the study of inertial confinement fusion (ICF), we analyzed a novel optical streak camera with ultrahigh time resolution. Based on the photogenerated carrier effect, waveguide transmission and prism dispersion principles, this alloptical device can avoid the influence of the space charge effect. The feasibility for the alloptical streak camera was confirmed with the experimental result. The module with prism structure to deflect the light in the waveguide was designed and fabricated. The deflection experiment was completed with the laser pulse of 8 ps (FWHM) under the condition of the signal laser wavelength of 1053 nm and the pump laser wavelength of 527 nm.
