Résumé

On the occasion of the 50th anniversary of the invention of the laser, this film retraces various aspects of this scientific discovery that brought about a revolution in our daily lives.
Laser (acronym for light amplification by stimulated emission of radiation) has established itself in many fields such as telecommunications, surgery, materials cutting technologies, distance measurements, bar code reading, etc. All of this had not anticipated at the time of its development. The history of laser technology perfectly illustrates how basic research can impact on science and on our daily lives as well.
After a historical part describing the various advances leading to the development in 1960 of the first ruby laser by Theodore Maiman, various applications of the laser and its operating principle are studied.
