The rest of this wonderful-to-be page is still in the rudimentary construction stage!! And God knows when I'll get to improve it!!

Laser Setup

 Click here for a slideshow of our experiments and models, and here for a somewhat more detailed overview of our theoretical work.

Presently, we are investigating, experimentally as well as theoretically, the occurrence and minimization of thermal stresses during laser machining of ceramics. If you have an mpegviewer, you can view/download several short movies showing the transient development of thermal stresses during laser drilling and scribing:

To understand the meaning of non-dimensional temperatures and non-dimensional stresses used in the above movie clips, check out this Postscript file.
