The First Optical Fiber Laser and Amplifier, 1961-1964

In 1961, Elias Snitzer and colleagues constructed and operated the world's first optical fiber laser in the former American Optical complex at 14 Mechanic Street. Three years later this team demonstrated the first optical fiber amplifier. Fiber lasers that can cut and weld steel have since become powerful industrial tools and fiber amplifiers routinely boost signals in the global optical fiber network allowing messages to cross oceans and continents without interruption.



Please also include references and full citations, and include supporting material in an electronic format (GIF, JPEG, PNG, PDF, DOC) which can be made available on the IEEE History Center’s Web site to historians, scholars, students, and interested members of the public. All supporting materials must be in English, or if not in English, accompanied by an English translation. If you are including images or photographs as part of the supporting material, it is necessary that you list the copyright owner.

Elias Snitzer, and colleagues developed the first working optical fiber laser and amplifier between 1961 and 1964 at the old American Optical plant in Southbridge MA. The development of the fiber laser drew from Snitzer's earlier work culminating in the first solid-state laser made of glass in 1961 plus his work in optical fibers in which he was the first to report the theory and observation of modes in an optical fiber. This ground-breaking combination of these two then-young technologies was many years ahead of its time.

This work is documented in the following articles:

Snitzer is shown here with a Nd-doped glass rod in a photo from the early 1960s. Historical images of the American Optical plant from that period are also shown below.

The advent of optical fiber amplifiers was vital in building the high-speed backbone of the global telecommunications network, which carries our words, pictures and data around the planet. More recently, fiber lasers have become powerful tools in manufacturing, generating multikilowatt beams that can cut and weld materials from plastics to metals.

What features or characteristics set this work apart from similar achievements?

Other early solid-state lasers, such as the ruby laser demonstrated by Theodore Maiman in 1960, another IEEE Milestone, were made of bulk materials. The fiber laser uniquely transmitted the light it generated along a light-guiding core, concentrating its energy in a small area inside the glass, and making it easy to transfer light from a fiber laser into a passive optical fiber for transmission. This became important when fiber-optic communications emerged in the 1970s, because optical signals needed to be amplified after passing through tens of kilometers of glass. Initially that required converting the signals into electronic form for amplification, but building upon Snitzer's work, subsequent researchers developed fiber amplifiers in the optical telecommunications wavelength band that could directly boost signal strength across a wide range of wavelengths, allowing high-speed transmission across continents and under oceans. This work is documented in a number of publications including the following articles which each refer to the earlier work by Snitzer:

Poole, S. B., Payne, D. N., and Fermann, M. E.: 'Fabrication of low-loss optical fibres containing rare-earth ions', Electron. Lett.,1985, 21, pp. 737-738, August 1985.

R. J. Mears, L. Reekie, I.M. Jauncey, D. N. Payne, "Low-Noise Erbium-Doped Fibre Amplifier Operating at 1.54um," Electronics Letters, Vol 23, No. 19, September 1987.

E. Desurvire, J. R. Simpson, P. C. Becker, "High-gain erbium-doped traveling-wave fiber amplifier," Optics Letters, Vol. 12, No. 1, pp. 888-890, November 1987.

This fiber amplifier technology is today the backbone of the global telecommunication network. Fiber lasers also have proved exceptionally well suited for efficiently generating high-quality beams with powers reaching many kilowatts in strength, greatly expanding the applications of lasers in cutting, welding and other machining of materials.
