激光标记系统属于掩模标记装置或行程标记装置两大类之一。一般而言,掩模标记装置使用TEACO_2激光器把掩模投射到工件上,而行程标记装置是利用Nd∶YAG激光器和扫描反射镜使很好聚焦的激光束在工件上移动。然 Laser marking systems belong to one of two broad categories of mask marking devices or stroke marking devices. In general, a mask marking device projects a mask onto a workpiece using a TEACO 2 laser, while a stroke marker moves a well-focused laser beam on a workpiece using a Nd: YAG laser and a scanning mirror.
