摘要
为了简化Nd∶YAG固体激光器谐振腔平行性的调节、提高效率及减小误差,将二维位置传感器(PSD)应用于平行性调节,配合设置的光路系统,运用放大电路采集谐振腔前后两表面反射至PSD上的光斑产生的电压值,并输入计算机中,得出光斑位置坐标值.据此微调其中一表面使2个坐标值相等,即谐振腔相对偏移量降至零,则表明激光器谐振腔平行.此方法将光电结合,平行度量化,且简单易行,操作方便.
In order to simplify the parallel adjustment of the resonator of Nd：YAG solid-state laser to improve efficiency and reduce errors,the usage of two dimensional position sensitive device（PSD）combined with the proper setting of the optical system was proposed.The spots reflected from both the front and rear surfaces of the cavity were captured by the PSD,the position coordinates of the two spots were then calculated.By adjusting one reflective surface to make the two position coordinates coincide,the parallelism of the two reflecting mirrors of the cavity could be realized.By utilized both optical and electrical techniques to give a quantitative criteria of the parallelism,this method was simple,practical and easy to operate.
