激光加工技术的工作原理可以分为激光产生、激光传输和激光加工等三个步骤。激光切割几乎可以加工所有材料，尤其在一些有特殊要求、特别场合和特种材料的加工制造方面起着无可替代的作用。</div><div><br></div><div> 激光加工成套设备是实现激光加工的基础，由激光器、数控系统、光学部件、<a href="http://machine.oecr.com" target="_blank" class="relatedlink">机械</a>部件、电气控制等几个部分组成。激光加工分为熔化切割、气体动力切割、电离切割等不同的加工方式，这些加工方式的选择取决于材料的类型、厚度和加工需求等因素。</div><div><br></div><div> 激光也是光的一种，不过不同于太阳光和其他光源，激光是<a href="http://theory.oecr.com" target="_blank" class="relatedlink">物理</a>原理形成的光源，是一种同向能量密度高、准直、高亮的光子束，甚至被称为“最快的刀”“最准的尺”。</div><div><br></div><div> 激光的产生是通过激光器实现的。激光器是一种将能量转换为激光光束的装置，它可以充当激发介质的能量源，使得激发介质向其外界的电磁场发射出激光光束。</div><div><br></div><div> 激光器的激发源是强光或电流，而激发介质则是气体、<a href="http://sensor.oecr.com" target="_blank" class="relatedlink">半导体</a>、<a href="http://material.oecr.com" target="_blank" class="relatedlink">晶体</a>等物质。激光传输是指激光从激光器输出到加工物体的过程，光学元件可以控制激光光束的直径、聚焦度、形状和强度等因素，以满足不同加工的需求。</div><div><br></div><div> 以激光切割为例，激光是原子受“激”时释放光子从而跃迁到低能级状态，被释放出的光子经过透镜聚焦后，与其他原子受激辐射释放的光子具有相同的电势能、频率、偏振状态和传播方向，从而产生高能态的，具有切割、熔化、改变物体表面性能等功能的光子束。</div><div><br></div><div><section microsoft="" yahei",="" simsun;="" margin:=""
