Twenty-one years ago, researchers at University of Colorado put the predictions of Satyendra Nath Bose and Albert Einstein to the test, resulting in the first gaseous condensate.
Known now as a Bose-Einstein Condensate, the state of matter refers to a diluted gas of bosons, which are cooled to temperatures close to absolute zero. When exposed to this temperature, the majority of the bosons are in the lowest possible quantum state. Once in this state, the bosons show quantum qualities at the macroscopic, rather than atomic level. This behavior is known as macroscopic quantum phenomena.
June 5th, 1995 saw the birth of […]
Using lasers to detect harmful bacteria is a topic of interest to more than a few researchers. Previously, we highlighted developments where lasers were used to identify contaminated food, which may be used to stop food poisoning long before contaminated food hits a dinner plate. Now, researchers at Purdue University have developed a laser tool that not only detects harmful bacteria, it also recognizes mutated strains.
The tool, known as bacteria rapid detection using optical scatter technology or BARDOT, works similar to the TDLAS method developed at the Institute of Information Optics, Zhejiang Normal University, Jinhua, China. BARDOT scans colonies of bacteria, […]
You wake up in the morning and the first thing you do is grab your cell-phone. You check your notifications and may even wonder why “this is the norm”. With the internet becoming more and more accessible and used more-often-than-not, it’s safe to believe that the internet isn’t leaving us anytime soon. Yet, the question still remains: where did the internet come from? The internet and the function of light-based signals can all be traced back to one major feat: fiber optics. Fiber optics, or optical fibers, are the components that helped create the internet and make international communications […]
Supermarkets and warehouses across the globe are participating in the ever-growing game of bar code scanning. Bar codes are used more often than not and for most items that you typically surround yourself with. Any item that is bought within a major grocery store, online, or go through warehouse processing will undergo some sort of scanning process in order to keep managers and those in charge informed of either an increase or decrease in a given numerical value associated with inventory.
A bar code, or universal product code (UPC), is a quick and efficient way of entering numerical data into […]
“Set phasers to stun!” As one of the most-beloved sci-fi series of all time, Star Trek has captivated generations. Often praised for its surprisingly accurate scientific applications, choosing to use the fictional “phaser” rather than a laser in the show and films seems uncharacteristic of the franchise. Find out why the creators of Star Trek ommitted the use of lasers in this week’s Science Fiction or Science Fact post by clicking here.
What if you could “print out” a laser so small and inexpensive, it is practically disposable? Research teams in France and Hungary have developed tiny laser systems, using inkjet […]
Out of context, “shooting lasers at the moon” sounds closer to the nefarious plot of a Saturday morning cartoon villain than a milestone in the history of lasers. The process is known as lunar laser ranging, which is the process of using lasers to measure the distance between the earth and the moon.
In May of 1962, a team from Massachusetts Institute of Technology (MIT) were the first to successfully project the beam onto the surface of the moon, and have it reflect back. The beam was directed at Albategnius, a long-identified, larger-sized crater on the moon’s surface.
As part of the […]
ORLANDO, FL, MAY 18, 2016 — From business owners to industry leaders and laser experts, the best and brightest in manufacturing gathered from April 25-27, 2016 in Atlanta, GA, for LIA’s most cutting-edge Lasers for Manufacturing Event® (LME®) and Summit yet.
Beginning on April 25 with the Summit at the Renaissance® Atlanta Waverly Hotel, and continuing with the two-day LME on April 26-27 at the adjacent Cobb Galleria Centre, the fifth installment of LIA’s comprehensive, three-day manufacturing event once again served as the premier hub for both companies interested in exploring the integration of laser technology into their production, and […]
Disposable, single-use items are used by the general public on an almost daily basis. Whether it’s cups, razors, or cleaning products, the ability to consistently have essentials on hand is a convenience for many around the world. When thinking of disposable items and products, lasers are far from the first thing that pops into one’s mind. Teams in France and Hungary are looking to change that perception by creating a small, printed (and possibly disposable!) laser system.
Using inkjet printing, the researchers have designed and developed laser systems that are so low-cost and efficient, they might as well be thrown […]
In the past, we looked at why lightsabers will likely never be holstered to our hips, unless we live in a galaxy far, far away. But what about in “the final frontier”? In the Star Trek universe, phasers are far more commonplace than laser-based weapons and technology. Today, we’re going to look at why the creators chose to use mostly phasers, over lasers, while also analyzing whether or not phasers are any more likely to exist than the mostly-debunked technology of the other space-adventure universe.
In the original series’ pilot, as well as some of the following episodes, lasers […]
This week we profiled Deborah Jin and the Fermionic Condensate. Dr. Deborah Jin is an American physicist and was among the first to study the Bose-Einstein condensate. Dr. Jin and team created the first fermionic condensate, a new form of matter. Unlike a Bose-Einstein condensate, a fermionic condensate contains fermions over bosons. This characterizes a fermionic condensate as a superfluid, a much more difficult state to obtain than that found in a Bose-Einstein condensate. Learn more by clicking here.
Speaking of Bose-Einstein condensate, we reflected on the birth of the Bose-Einstein condensate, back in 1995. First theorized by Albert Einstein and […]
