Fifty years of the 'light fantastic:' Laser advances spark scientific progress

11.03.2010
Fifty years after the first laser sparked a technological revolution, the "light fantastic" continues to impact people's daily lives — by playing DVDs, speeding Internet connections, and performing intricate surgery.

As the golden anniversary of the announcement of the first laser approaches on July 7th, Chemical & Engineering News (C&EN), ACS' weekly newsmagazine, takes a special look at the past, present, and exciting future of this amazing invention.

C&EN Senior Editor Mitch Jacoby and Assistant Editor Lauren Wolf point out that the laser has come a long way since it was first demonstrated in 1960 by Theodore Maiman. Although few people at the time could have envisioned how the device would be used, he accurately predicted that lasers would impact diverse areas ranging from industry to science. Today, the laser has become a "workhorse tool" in modern chemistry. Scientists now use it to study climate change, ultrafast chemical reactions, and disease-related proteins. Researchers are also using lasers to see inside living cells.

More advances are on the way. Scientists are developing a laser-based system for remotely detecting nerve agents and other harmful chemical and biological warfare agents. Others are developing a laser-based medical instrument that could allow earlier detection of hard-to-diagnose diseases such as lung and bladder cancers. Only time will tell what the next 50 years will bring, the article notes.

Im Focus: Fizzy soda water could be key to clean manufacture of flat wonder material: Graphene

Whether you call it effervescent, fizzy, or sparkling, carbonated water is making a comeback as a beverage. Aside from quenching thirst, researchers at the University of Illinois at Urbana-Champaign have discovered a new use for these "bubbly" concoctions that will have major impact on the manufacturer of the world's thinnest, flattest, and one most useful materials -- graphene.

As graphene's popularity grows as an advanced "wonder" material, the speed and quality at which it can be manufactured will be paramount. With that in mind,...

Im Focus: Exotic quantum states made from light: Physicists create optical “wells” for a super-photon

Physicists at the University of Bonn have managed to create optical hollows and more complex patterns into which the light of a Bose-Einstein condensate flows. The creation of such highly low-loss structures for light is a prerequisite for complex light circuits, such as for quantum information processing for a new generation of computers. The researchers are now presenting their results in the journal Nature Photonics.

Light particles (photons) occur as tiny, indivisible portions. Many thousands of these light portions can be merged to form a single super-photon if they are...

Im Focus: Circular RNA linked to brain function

For the first time, scientists have shown that circular RNA is linked to brain function. When a RNA molecule called Cdr1as was deleted from the genome of mice, the animals had problems filtering out unnecessary information – like patients suffering from neuropsychiatric disorders.

While hundreds of circular RNAs (circRNAs) are abundant in mammalian brains, one big question has remained unanswered: What are they actually good for? In the...

Im Focus: RAVAN CubeSat measures Earth's outgoing energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth's climate.

The Radiometer Assessment using Vertically Aligned Nanotubes (RAVAN) CubeSat was launched into low-Earth orbit on Nov. 11, 2016, in order to test new...

Im Focus: Scientists shine new light on the “other high temperature superconductor”

A study led by scientists of the Max Planck Institute for the Structure and Dynamics of Matter (MPSD) at the Center for Free-Electron Laser Science in Hamburg presents evidence of the coexistence of superconductivity and “charge-density-waves” in compounds of the poorly-studied family of bismuthates. This observation opens up new perspectives for a deeper understanding of the phenomenon of high-temperature superconductivity, a topic which is at the core of condensed matter research since more than 30 years. The paper by Nicoletti et al has been published in the PNAS.

Since the beginning of the 20th century, superconductivity had been observed in some metals at temperatures only a few degrees above the absolute zero (minus...
