The History Of The Laser: Updated copy, 2012
Written and told by Ali Javan, on the occasion of our now commemorating the 50th anniversary of the lasers presently. Having a beginning of it in a historic event as it took place on 12th December the year 1960, at 4:20 PM. Where, and for the first time in the history of the lasers, there emanated from the output, of what proved as the original historic gas discharge laser light source, a collimated propagating 'continuous wave', CW laser light beam. A CW laser light beam with a color purity and an accuracy and for the first time, as the laws of nature will permit: the original historic Hellum Neon gas discharge laser light source, operating as told on 12th December 1960 — at 4:20 PM and that which initiated and as shall be told, a beginning in much that followed thereafter in lasers and by now 5 decades since.


Yet: This now historic event however, proved to have itself a historic beginning. Which by as a full decade of much that took place in this extended period of a decade, through and up to the historic 12th December 1960 event itself.


The history of the laser 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.


The history of the laser told here, is an exciting story of which not much is known.

This website shall tell that story in what shall follow presently.
Ali Javan, is Professor of Physics at Massachusetts Institute of Technology, emeritus presently.

      The following passage is from Professor Ali Javan's MIT Bio sketch reproduced here, which reads:
Professor Javan is the first Named Francis Wright Davis Professor of Physics at Massachusetts Institute of Technology. He is recognized for his original contributions and, for his considered leadership in the field of lasers and quantum electronics. He won international acclaim for his original invention of the world first laser capable to operate continuously, and to operate at an unprecedented color purity and accuracy.

He conceived the working principle of this original laser and predicted its potential early in the summer of the year 1958—as it took place at a time nothing was known of lasers. And while a member subsequently of the research staff at the Bell Telephone Laboratories in Murray Hill, New Jersey, he initiated an extended research with much anticipation at the Bell laboratories, and successfully succeeded to operate this original laser on December 12th, 1960. The well-known historic Helium Neon gas discharge laser light source operated, for this very first time, at its unprecedented color purity and accuracy.

This original invention is as well as the first to operate continuously, is the very first just as well, to operate on the principle of converting the electrical energy in a light emitting gas discharge serving as a light source—to a coherent collimated laser light beam, at its unprecedented accuracy and color purity. The discovery soon attracted worldwide attention, and as it proved, initiated much that followed in lasers thereafter.
Yet however, little is known of an exciting historic event as it took place within weeks time following this original historic invention of 12th December the year 1960. And as what took place in this weeks time initiated much that followed in lasers thereafter and throughout the time—and up to the present. And hence, it is called-for that we give an account of what took place here, of much interest presently.
There always is as it seems, an exciting story in an invention of special significance as in here. And which shall have to be told.
And, as an added note to keep in mind, what shall be told and covered here presently, are mainly from the records of this original historic invention, as referenced and told in what follow presently.
