A new method to investigate the transmission characteristics of laser in water which based on virtual instruments technology

将虚拟仪器技术运用于激光在水中传输规律探索。测量了不同能量的光束,通过不同长度的水介质在窄线宽与宽线宽两种情况下的衰减系数,研究了受激布里渊散射对激光在水中衰减特性的影响。利用功能强大的LabVIEW软件对各种先进仪器进行综合控制,然后对采集到的水中传输激光能量信号进行处理,不仅提出了一种实时检测水的衰减系数的新方法,并且对激光监测系统的设计提供必要的理论及应用基础。

Using virtual instruments technology to investigate the Attenuation characteristics of laser in water. Through different sample length the attenuation coefficient of laser beam with different pulse energy is measured experimentally in water. And, the effect of stimulated Brillouin scattering on the attenuation characteristics of water is studied. By using the powerful LabVIEW software, we can control all the advanced instruments, and process the Laser energy signal we have acquired from water. It will provide either the theory or application basics for the design of Laser Monitoring System.
