Drilling Laser

JK Lasers, a division of GSI Groups, has released its enhanced pulsed Nd:YAG JK604D laser, designed for the percussion drilling and trepanning of a selection of components in the automotive and aerospace industries. The instrument provides peak powers for aerospace drilling applications and is designed to offer maximum pulse energy and an improved beam quality. The beam produces high-quality hole profiles, while the high-intensity laser spots allow for fast drilling and removal rates. A new resonator design provides a much wider operating window than previous drilling lasers in this class, enabling a more flexible approach to manufacturing parameters and shorter times to optimize a new process. Applications include fast trepanning of 0.3- to 0.8-mm holes in <1 s, deep drilling using a long depth of focus, and shaped-hole and on-the-fly drilling.

depth of focus
The range of image distances that corresponds to the range of object distances covered by the depth of field.  
A volume, bounded at least in part by highly reflecting surfaces, in which light of particularly discrete frequencies can set up standing wave modes of low loss. Often, in laser work,the resonator contains two facing mirrors that may either be flat (Fabry-Perot resonator) or have some spherical curvature, which together bind the lasing material that is referred to as the gain medium, and hence the optical cavity of a laser is where lasing occurs.
