柱面波导静态线性光束优化系统研究

Research on steady linear laser beam optimum system with cylindrical and waveguide mirrors

采用两组柱面镜和一维波导镜组合,设计了一种具有光束聚焦及展宽功能的新型激光束优化系统.并用800WYAG激光器和2000WCO2激光器进行了这一装置的实用效果观察.结果认为,光强基本均匀,淬火面平整,线光斑宽度在15～25mm内无级可调.

A new kind of system, which consists of two perpendicular cylindrical mirrors and 1D waveguide mirror is presented, in which the primary circle laser beam can be changed into a linear pattern in the line focus. Some experiments in YAG laser and CO2 laser are made. The result shows the new laser beam optimum principles and installation is useful. The laser energy density distribution is homogeneous on the whole, and the mark of end quench section of material is smath, and the width of the line can be adjusted from 15 mm to 25 mm.
