X射线条纹相机紫外光时标研究
STUDY OF UV LASER FIDUCIAL MONITOR FOR X RAY STREAK CAMERA
-
摘要: 报导了一种采用超短紫外光脉冲作为X 射线条纹相机时标系统的方法。时标光脉冲来自用多模石英光纤耦合的波长为1.06μm 四倍频超短紫外光脉冲激光系统。时标光脉冲与打靶产生的X 射线均被X 射线条纹相机接收, 以用来测定激光打靶时X 射线产生的相对时间关系或相机之间同步的时间关系。实验得到通过光纤引导的时标光脉冲宽度约为30ps。Abstract: A method is used in fiducial monitor research by using ultrashort UV optical pulse as fiducial monitor for X ray streak camera, which fiducial optical pulse was from fourth harmonic system of 1.06μm Nd:YAG laser. This fiducial optical pulse and X-ray emission have been received by X ray streak camera so as to precisely relate the X ray emission to the incident laser pulse or these cameras. Fiducial optical pulse with 30ps is measured using UV streak camera.
