Gordon Gould and the Term 'LASER'

Gordon Gould coined the term "LASER" as an acronym for "Light Amplification by Stimulated Emission of Radiation" in 1957, documenting it in a notarized notebook. He adapted it from Townes's existing "MASER" acronym. Despite inventing the concept, he spent 28 years fighting in court before earning recognition, and his patents eventually covered components inside 80% of industrial lasers. He never won a Nobel Prize, but there's much more to his fascinating story.

Key Takeaways

• Gordon Gould coined the term "LASER" as an acronym for "Light Amplification by Stimulated Emission of Radiation" in 1957.
• Gould adapted the term from Charles Townes's existing "MASER" acronym, simply replacing "Microwave" with "Light."
• He documented his laser concept in a notarized notebook on November 13, 1957, including sketches and equations.
• This notarized notebook became the foundation of a grueling 30-year patent battle against the laser industry.
• Despite inventing the term, Gould spent 28 years in court watching others profit before receiving recognition and compensation.

Who Was Gordon Gould, the Man Behind the Laser?

Gordon Gould was born on July 17, 1920, in New York City, and from an early age, he idolized inventors like Thomas A. Edison. These formative childhood influences shaped his passion for science and discovery.

He pursued his curiosity academically, majoring in physics at Union College, where he earned his bachelor's degree in 1941. His early academic achievements continued when he received his master's degree in physics from Yale University in 1943.

You'd find his graduate work particularly impressive, as he focused on optical and microwave spectroscopy. He later taught physics at City College of New York and studied at Columbia University, working alongside Charles Townes on ideas that would eventually contribute to one of the most transformative technologies in modern history — the laser. He was the oldest of three sons born to his mother Helen Vaughn and his father Kenneth Gould, who was the founding editor of Scholastic Magazine Publications.

Gould came up with the idea of the laser and its name in 1957, and he is credited with coining the term laser as an acronym, standing for light amplification by stimulated emission of radiation.

How Did Gould Coin the Term "LASER" in a Single Notebook?

One November night in 1957, a single idea jolted Gordon Gould awake in his Bronx apartment. He sat bolt upright, moved to his desk, and opened his laboratory notebook. What followed was an overnight brainstorming session that produced something remarkable: the spontaneous terminology coinage of "LASER," standing for Light Amplification by Stimulated Emission of Radiation.

You can see Gould's genius in how he adapted Townes's existing "MASER" acronym, simply swapping "Microwave" for "Light." His November 13th notebook entry captured sketches, equations, and feasibility calculations, all documenting this conceptual leap. He later had the notebook notarized, a decision that proved critical. That single document became the cornerstone of 30 years of patent battles and ultimately secured him royalties from 80% of industrial laser applications. Despite his groundbreaking work, Gould's lack of a PhD or prestigious awards made it significantly harder for him to prove his claim as the true inventor of the laser.

Gould's journey was further complicated when he was denied security clearance due to his radical background, preventing him from working on his own invention and handing a significant advantage to his rivals in the race to develop the laser.

How Did a 20-Year Patent Battle Define Gould's Career?

That notarized notebook Gould filled in November 1957 didn't just coin a term—it sparked a legal war that consumed the next three decades of his life. His first mistake was waiting to file, wrongly believing he needed a working prototype first. That delay handed Townes and Schawlow a head start, and competing labs quickly flooded the Patent Office with overlapping claims.

The legal challenges faced by Gould only intensified when the laser industry actively fought to revoke his already-granted patents. He battled simultaneously in federal court and Patent Office proceedings against multiple manufacturers. His strategic shift in patent applications, narrowing claims toward specific commercial uses after 1977, finally started turning the tide—but by then, Gould had spent his career fighting for an invention the world had already embraced. Gould and Patlex won their first suit to collect royalties in 1987, when Control Laser ultimately settled by surrendering the company itself to Gould.

Throughout this prolonged legal battle, Gould made significant personal sacrifices, including selling his 45-foot yacht to fund the ongoing patent fight that had already consumed both his finances and his peace of mind.

How Did Gould's Patents End Up Inside 80% of Industrial Lasers?

After two decades of legal setbacks, Gould's 1977 strategic pivot changed everything. Instead of claiming the complete laser, he focused his patent strategy on the optical amplifier — the core component inside every laser. This patent strategy focus proved brilliant. By targeting the essential building block rather than the overall device, his patents suddenly applied to 80% of industrial, commercial, and medical laser applications.

His technical description overcoming earlier failures also mattered enormously. Using a notarized 1957 notebook, he established clear precedence, and his patents expanded to cover optically pumped, discharge-excited, and collisionally pumped laser amplifiers, plus fiber optic communications. Inducted in 1991, Gould was formally recognized for these groundbreaking contributions when he was welcomed into the National Inventors Hall of Fame.

When the laser market hit $1 billion annually in 1982, you can see why industries fought hard — and ultimately lost — to avoid paying Gould his royalties. Before any of this success, Gould had filed for patent on laser technology in 1959, only to face a grueling series of five separate interferences from the Patent Office that delayed recognition of his invention for nearly two decades.

Did Gordon Gould Ever Get Credit for Inventing the Laser?

Gordon Gould's story doesn't have a clean, triumphant ending — and that's what makes it so fascinating. He was ultimately recognized as laser inventor through his patents and his 1991 induction into the National Inventors Hall of Fame. His legal victory leading to widespread use proved that his 1957 notebook wasn't just historical curiosity — it was documented proof of priority.

But the Nobel Prize went to Charles Townes in 1964, and historians still debate who deserves full credit. Gould never earned his Columbia Ph.D., spent 28 years fighting in court, and watched others profit from his ideas before he did. You could call it a partial victory — enough to reshape patent law, but never quite enough to settle the argument completely. Meanwhile, Bell Labs was awarded the original laser patent that Gould had applied for, setting the stage for decades of legal conflict.

Despite the long road, Gould did experience a significant financial breakthrough when he received a $1.2 million down payment from a licensing agreement in November 1987, finally seeing tangible returns from his decades of persistence.
