Lasers
I watched, on the discovery channel a show which involved lasers. ... It dealt with lasers for patients in hospitals and lasers in general. The light from lasers differs from ordinary light in several importan aspects. ... We now have a neon tube but not a laser so lets take a closer look at how the lasers light is produced. ... Lasers are very different from neon tubes in that they amplify the glowing effect via stimulated emission. ... In most HeNe lasers the mirrors are permanently attached or sealed onto the ends of the tube -- sometimes referred to as hard seal technology. In higher power lasers the mirrors are usually not mounted on the ends of the tube itself, but on an external resonator that forms part of the laser frame. ... Some types of lasers do have a cycle where energy is pumped into the lasing medium, then released in a short burst of laser energy.
