The laser is a marvelous device that sends out a slender,
concentrated beam of light, a light that surpasses the
light at the sun’s surface. So vast is the laser beam’s power
that it has without a doubt the capacity to vaporize*
any substance located anywhere on earth. The laser can penetrate
steel, pierce a diamond, or make an accurate
die for wire so thin that it can be seen only with a microscope.
Grateful eye surgeons report that they have used laser beams to repair the
retinas in some fortunate* patients by creating tiny scars that joined
the retina to the eyeball. Pioneering* medical men are making cautious
exploration* into cancer cures with the laser, confident
that they will alter* the course of this brutal* disease.
