较完善的激光刻线系统在本世纪70年代末才问世,激光技术可称为当今最新的加工方法之一,它在材料加工、医学、测量及科学研究等领域有着广泛的前景。激光器的主要部分是抽运腔,腔内装有一个4～5mm粗的晶棒,在椭圆形的镀金腔中有一个3.5kW的氪光灯。从灯光发出的光照射在棒的中心,然后光经过两个反光镜射回晶体棒,这个包含抽运腔和反光镜的结构称为谐振器。反光镜是半透明的。因此,允许激光束从谐振器发射出来。用装在谐振器上的一个声光开关能将输出的激光调大到25kHz频率。激光刻线是采用向量法工作的,即光束借助于由
The perfect laser engraving system came out in the late 1970s. Laser technology can be regarded as one of the latest processing methods. It has a wide range of prospects in materials processing, medicine, measurement and scientific research. The main part of the laser pump cavity, the cavity is equipped with a 4 ~ 5mm thick ingot, in the oval gold plated cavity has a 3.5kW krypton light. Light from the light shines through the center of the rod and the light returns to the crystal rod through two reflectors. The structure containing the pumping chamber and the reflector is called a resonator. Mirror is translucent. Therefore, the laser beam is allowed to be emitted from the resonator. A sound and light switch mounted on the resonator can be output to the laser up to 25kHz frequency. Laser scribing is the use of vector method that the beam by means of
