当激光束与材料碰撞时,激光脉冲将材料加热、熔化并蒸发。在这一过程中,蒸发物质的体积迅速增加。产生的压力迅速将蒸发的物质排出,留下激光钻出的孔。脉冲中的能量越大,孔就越大,这可以非常精确地控制。激光钻孔允许非常精确的位置和准确的孔尺寸。脉冲激光器可以被小心地控制和快速地充电。这些特性使其能够在给定的时间内以较高的速度进行钻井。它简单、干净、快捷。这是激光钻孔最基本的形式。这一过程导致了激光钻孔的几种变化,包括冲击钻、套钻和螺旋钻。 Percussion drilling is fairly similar to single pulse. Instead of using one burst of energy, it reduces the power and uses several shorter bursts at the lower energy. Using the percussion method, holes can be deeper, more accurate, and hole diameters can be made even smaller due to less material vaporizing with each rapid pulse
