Researchers have developed an ultrafast fiber laser that delivers an average power more than ten times what is available from today’s high-power lasers. The technology is poised to improve industrial-scale materials processing and paves the way for visionary applications.


Michael Müller, a Ph.D. student of Prof. Jens Limpert from the Friedrich Schiller University’s Institute of Applied Physics and the Fraunhofer Institute of Institute for Applied Optics and Precision Engineering in Jena, Germany, will present the new laser at the all-virtual 2020 OSA Laser Congress to be held 12-16 October. The presentation is scheduled for Tuesday, 13 October at 14:30 EDT.

High power without the heat

In lasers, waste heat is generated in the process of light emission. Laser geometries with a large surface-to-volume ratio, such as fibers, can dissipate this heat very well. Thus, an average power of about 1 kilowatt is obtained from today’s high-power

Scientists record last moments of star devoured by black hole — ScienceDaily

A rare blast of light, emitted by a star as it is sucked in by a supermassive black hole, has been spotted by scientists using telescopes from around the world.

The phenomenon, known as a tidal disruption event, is the closest flare of its kind yet recorded, occurring just 215 million light-years from Earth. It is caused when a star passes too close to a black hole and the extreme gravitational pull from the black hole shreds the star into thin streams of material — a process called ‘spaghettification’. During this process some of the material falls into the black hole, releasing a bright flare of energy which astronomers can detect.

Tidal disruption events are rare and not always easy to study because they are usually obscured by a curtain of dust and debris. An international team of scientists led by the University of Birmingham were able to study this

ESO telescopes record last moments of star devoured by a black hole — ScienceDaily

Using telescopes from the European Southern Observatory (ESO) and other organisations around the world, astronomers have spotted a rare blast of light from a star being ripped apart by a supermassive black hole. The phenomenon, known as a tidal disruption event, is the closest such flare recorded to date at just over 215 million light-years from Earth, and has been studied in unprecedented detail. The research is published today in Monthly Notices of the Royal Astronomical Society.

“The idea of a black hole ‘sucking in’ a nearby star sounds like science fiction. But this is exactly what happens in a tidal disruption event,” says Matt Nicholl, a lecturer and Royal Astronomical Society research fellow at the University of Birmingham, UK, and the lead author of the new study. But these tidal disruption events, where a star experiences what’s known as spaghettification as it’s sucked in by a black hole,

Commercially Available Silicon Quantum Computer Moves Forward With Quietest Bits On Record

KEY POINTS

  • Physicists achieve a noise level 10 times lower than the previous record
  • Demonstration proves to take a major step closer to a full-scale silicon quantum processor 
  • Next step could be a 10-qubit prototype quantum integrated processor by 2023

The lowest noise level on record for a semiconductor quantum bit has been demonstrated by a team of quantum physicists, bringing the development of a commercially available silicon quantum computer one step forward to possibility. 

In a study published in Advanced Materials, the physicists said they were able to achieve a noise level 10 times lower than previously recorded for any semiconductor qubit. Specifically, they demonstrated a low-level charge noise of  S0 = 0.0088 ± 0.0004 μeV2 Hz−1. 

As a next step, the team is now looking forward to demonstrating the capability required to produce a reliable 10-qubit prototype quantum integrated processor by 2023. 

“Our team is now working towards

PC Sales Just Broke A 10-Year Record Thanks To The Pandemic

The global PC market grew by almost 13% in the third quarter, according to Canalys, marking the biggest surge in sales in the last decade.

According to the analyst firm’s estimates, shipments of PC and laptop devices reached 79.2 million units during the quarter, an increase of 12.7%, as sales “continued to benefit hugely from the COVID-19 crisis”.

Laptops accounted for the majority fo these sales, with 64 million units shipped during the third quarter as employees continue to work from home. Laptop and mobile workstation shipments also saw sales increased by 28.3% year over year, though desktop and desktop workstations saw a 26% decline in shipments.

“Vendors, the supply

Wealth Management M&A Activity Surges To Record Levels

The third quarter of 2020 will be remembered as one of the most unique periods of merger and acquisition activity in the history of the wealth management industry.

There were a record number of deals in Q3 – 55 transactions in total, according to the latest ECHELON Partners RIA M&A Deal Report – which surpasses the previous high of 53 deals that our research tracked in Q4 2019.

This record period comes directly after just 35 deals took place in Q2. This 57% increase in quarter-over-quarter M&A activity also registers as one of the sharpest increases in the industry’s history, marking a major rebound after the COVID-19-related market declines delayed and prolonged normal deal-making activity, as the figure below illustrates:

IT Giant TCS Surges to Record After Unveiling $2 Billion Buyback

(Bloomberg) —

Tata Consultancy Services Ltd. surged to a record high after the Indian giant announced a share buyback of as much as 160 billion rupees ($2.2 billion) and said technology spending was recovering faster than anticipated.

Asia’s largest software outsourcing provider reported a larger-than-expected 7% fall in net income to 74.7 billion rupees in the September quarter. But Chief Executive Officer Rajesh Gopinathan said IT budgets were bouncing back and growth should accelerate as clients spend on digital services such as cloud migration, security and work tools to trim costs and adjust to a post-pandemic environment.

September 2020 Was Warmest On Record, Arctic Sea Reaches Second Lowest Extent

September 2020 was the warmest September on record globally, according to scientists at the European Union’s Earth observation program Copernicus. The agency also revealed that the Arctic sea ice is at its second lowest extent since satellite records began in 1979.

September temperatures were well above average in many regions across the globe, including off the coast of northern Siberia, in the middle East, in parts of South America and Australia, with the exception of eastern tropical Pacific. The month was 0.05 C warmer than September 2019, the previous warmest September on record.

Scientists Say 2020 May Smash Heat Record

(Bloomberg) — Climate scientists warned 2020 could be the world’s hottest year on record, with September temperatures eclipsing previous highs and Arctic ice retreating from the seas it usually covers.

Global year-to-date temperatures show little deviation from 2016, the warmest calendar year recorded so far, Europe’s Copernicus Climate Change Service reported on Wednesday. Climate patterns like La Niña in the Pacific Ocean, occurring for the first time in eight years, could determine whether this year turns out to be the warmest on record, according to the researchers.

In September, temperatures reached 0.63 degrees Celsius (1.15 degrees Fahrenheit) above the 30-year historical average, with the Siberian Arctic and southeastern Europe in particular feeling the warming effects of climate change. Arctic sea ice reached its second-lowest extent for September, continuing a fast decline since satellites started monitoring the ice in 1979.

“There was an unusually rapid decline in
