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: Significantly more productivity in USP lasers

In recent years, lasers with ultrashort pulses (USP) down to the femtosecond range have become established on an industrial scale. They could advance some applications with the much-lauded “cold ablation” – if that meant they would then achieve more throughput. A new generation of process engineering that will address this issue in particular will be discussed at the “4th UKP Workshop – Ultrafast Laser Technology” in April 2017.

Even back in the 1990s, scientists were comparing materials processing with nanosecond, picosecond and femtosesecond pulses. The result was surprising:...

Im Focus: Shape matters when light meets atom

Mapping the interaction of a single atom with a single photon may inform design of quantum devices

Have you ever wondered how you see the world? Vision is about photons of light, which are packets of energy, interacting with the atoms or molecules in what...

Im Focus: Novel silicon etching technique crafts 3-D gradient refractive index micro-optics

A multi-institutional research collaboration has created a novel approach for fabricating three-dimensional micro-optics through the shape-defined formation of porous silicon (PSi), with broad impacts in integrated optoelectronics, imaging, and photovoltaics.

Working with colleagues at Stanford and The Dow Chemical Company, researchers at the University of Illinois at Urbana-Champaign fabricated 3-D birefringent...

Im Focus: Quantum Particles Form Droplets

In experiments with magnetic atoms conducted at extremely low temperatures, scientists have demonstrated a unique phase of matter: The atoms form a new type of quantum liquid or quantum droplet state. These so called quantum droplets may preserve their form in absence of external confinement because of quantum effects. The joint team of experimental physicists from Innsbruck and theoretical physicists from Hannover report on their findings in the journal Physical Review X.

“Our Quantum droplets are in the gas phase but they still drop like a rock,” explains experimental physicist Francesca Ferlaino when talking about the...

Im Focus: MADMAX: Max Planck Institute for Physics takes up axion research

The Max Planck Institute for Physics (MPP) is opening up a new research field. A workshop from November 21 - 22, 2016 will mark the start of activities for an innovative axion experiment. Axions are still only purely hypothetical particles. Their detection could solve two fundamental problems in particle physics: What dark matter consists of and why it has not yet been possible to directly observe a CP violation for the strong interaction.

The “MADMAX” project is the MPP’s commitment to axion research. Axions are so far only a theoretical prediction and are difficult to detect: on the one hand,...
