The Laser from Greatest Inventions of All Time

The history of the laser inventions that changed the world is an exciting story told here. Often taking place itself within an exciting ongoing story itself, of which little is known, and shall have to be told. And that further as one exciting event that shall have to be told here is that of the historic origin of the 'optical pumping effect'. And that which proved to have its original beginning long-before the lasers. In what took place, so unexpectedly yet, at CNRS in Paris originally — in as early as 1947. And yet following much that took place which lead to the discovery of the crystalline Ruby, that of ruby R Line which proved to have an optical gain of special interest. Having its origin — in the discovery of the 'optical pumping effect', and long before the lasers. An exciting story as shall have to be told.
