Holograms on charge cards and identification cards make them less easy to forge. Holography gives clear underwater pictures and lets pilots see their instruments without looking down at them. Holography lets physicians view broken bones, human organs, and the back of the eye. Work Performed Laser technicians produce and work with lasers. Laser test technicians test lasers.
Holographic technicians make holograms.
Since many of their duties are similar, the term technician in this brief applies to all three workers. Technicians work under the guidance of scientists or engineers who do research and develop or design lasers and laser applications. These technicians may work alone or as members of a team to use, test, repair, and maintain different kinds of lasers and the systems that use them. To build a solid-state laser, laser technicians first rotate a small crystal in a heated chemical mixture. The mixture builds up on the crystal layer by layer to form a rod.
