>3. How would & what is the best way/method of containing the laser beam, after > it penatrates the material, OR if the beam is running & there isn't any > material to penatrate. Well, assuming that a lens is used to focus the laser beam at one point, you could place a solar cell beyond the focal point of the lens to recirculate the power pumped into the laser. Or, you can actually couple some of the beam energy back into the laser. Just suggestions... ------------------------------------------------------------------------- John C.
