    50th Anniversary of Supercontinuum Laser Marked at SPIE’s BiOS/Photonics West

    Article obtained from Photonics RSS Feed.

    Light is one of the most vital and versatile phenomena in nature with salient properties. Without it, no one can see. And because of it, short pulses of light can reveal what’s hidden in the molecular world.

    That belief drove one of the seminal discoveries of the 20th century: supercontinuum light.

    Five decades ago, Robert Alfano, Ph.D., and Stanley L. Shapiro, Ph.D., both members of GTE Lab in Bayside, N.Y., observed a type of laser light that spanned a large part of the visible spectrum over 10,000 cm−1 under excitation of 532 nm green picosecond pulses. The observations were chronicled in three separate papers appearing in Physical Review Letters in 1970.

    “It was essentially a light bulb. I called it…
