Bench Degree·LASERSchapter

On the Cover

How the cover of every Bench Degree volume is chosen. One question, and it is not who got there first or who is famous. If we could bring anyone back to teach you this subject, who would you actually want at the bench? That is the whole test. It picks people who did the work with their hands, who checked things themselves, and who would be worth standing next to. Every one of them actually lived, which is why a cover portrait in this series is either a real document or openly a drawing, and never a photograph of something that did not happen.

Theodore Harold Maiman, engraved from an Associated Press photograph of 1964, at thirty-seven, leaning over his own bench.

He is here because of what he did in the nine months before that photograph was taken, and because of two things that happened afterwards.

In May 1960 he made the first laser work. He did it at Hughes Research Laboratories on a small budget, in about nine months, using a rod of synthetic ruby and a photographic flashlamp. He was competing against Bell Labs, IBM, General Electric, RCA, Westinghouse, Siemens, Lincoln Laboratory and others, all better funded and all chasing the same result.

And he did it with a material the field had written off. The published view, including work by people who would later share a Nobel Prize, was that ruby was unsuitable. Maiman measured it himself, found the numbers in the literature were wrong, and built the thing anyway. That is the argument of this whole series in one decision: he checked, rather than deferring.

Then, on 22 June 1960, he submitted the paper announcing it to Physical Review Letters. It was rejected in two days. The editor suggested an applied physics journal would give him a more appreciative audience. He cut it down and sent it to Nature, which published it that August as Stimulated optical radiation in ruby.

The paper announcing the laser was turned down by the leading physics journal of its day in under forty-eight hours.

About the photograph, and about the far more famous one that is not on this cover.

The cover is a real Associated Press photograph from 1964, converted to line work by a program that sets each engraving stroke’s thickness from the local tone of the original. Nothing in it was generated, retouched or invented. He is looking down at his own bench, which is not how a cover portrait is usually posed and is exactly right for this series.

The photograph everybody knows is a different one, and it is a staged prop.

The famous image of Maiman was taken on 7 July 1960 at the press conference where Hughes announced the invention, and it shows him holding a laser apparatus up in front of his mouth. That apparatus is not the first laser. The photographer hired for the announcement looked at the real device, decided it was too small to make an impression, and handed Maiman a larger later prototype instead, telling him to hold it in front of his face because the genuine article “won’t go anywhere.”

The consequences were not trivial. Newspapers ran melodramatic headlines. Other researchers, unable to square the picture with the paper, doubted the result. And Bell Labs used the published photograph as a reference to build their own ruby laser, working from a picture of a machine that was not the one that had worked.

So the most widely reproduced image of the first laser is a photograph of a bigger, later stand-in, staged because the real invention looked too modest. It seemed wrong to put that prop on the cover of a book about checking things yourself, and cropping it away leaves so little of him that you could not pick him out of a room. So the 1960 frame is not used at all, and the 1964 one is, with nothing in it but the man.

Why this book cares so much about a photograph.

Every person who appears on the cover of a Bench Degree volume actually lived, actually did the work, and can be misrepresented by an image they never sat for. So the rule for this series is that a cover portrait is a document or it is openly a drawing, and it is never a photograph of something that did not happen.

There was an easy way to use the famous photograph anyway: hand it to a generative model and have it paint out the tube. We did not do that, and the reason is that the tube covers his mouth and jaw. Removing it means a model inventing the lower half of a real man’s face. That is not retouching a background. It is manufacturing features, on a person who cannot object, in a book that argues for honest disclosure. Choosing a different photograph loses nothing. A generated fill adds information that never existed, and only one of those is honest.

The same rule ruled out the obvious alternative too. The 1964 photograph shows him working over laboratory apparatus, and this series cannot establish that the apparatus in that frame is the ruby laser rather than something else on the bench that day. Putting an unidentified machine on this cover would repeat the exact error the 1960 press photograph made. So the apparatus is cropped out of frame, and what is left is a man and a wall.
