图为激光焦点分析仪的测试结果,多模光纤激光器为加工头供能所形成的环形光斑几何形态如图a)所示,可得两束半环形光束在y轴正方向发生位移错位;由图b)可得环形光能量更多地集中在y轴正方向;除此之外,两束半环形光几何形态相对规则、尺寸对称。
The figure shows the results of the laser focus analyzer. The geometry of the annular spot formed by the multimode fiber laser supplying energy to the processing head is shown in Figure a), which shows that the two semi-annular beams are misaligned in the positive direction of the y-axis; from Figure 6b), the annular light energy is more concentrated in the positive direction of the y-axis; in addition, the geometry of the two semi-annular beams is relatively regular and symmetrical in size.
