X-ray lasers: Why does brighter mean darker?
When we illuminate something, we usually expect that the brighter the source we use, the brighter the resulting image will be. This rule also works for ultra-short pulses of laser light—but only up to a certain intensity. The answer to the question.....»»
A new milestone for laser technology: Seeded free-electron lasers
Extremely intense light pulses generated by free-electron lasers (FELs) are versatile tools in research. Particularly in the X-ray range, they can be deployed to analyze the details of atomic structures of a wide variety of materials and to follow fu.....»»
Using lasers to bond semiconductor electronics components
Today, lasers are well-established in daily life, even if it is sometimes hard to tell what and where they are. As an example, we can find them in CD/DVD readers or medical applications like cancer and eye surgery, being essential tools in a vast ran.....»»
New chip-scale laser isolator opens new research avenues in photonics
Lasers are transformational devices, but one technical challenge prevents them from being even more so. The light they emit can reflect back into the laser itself and destabilize or even disable it. At real-world scales, this challenge is solved by b.....»»
Image: Hubble glimpses a glittering gathering of stars
This glittering gathering of stars is Pismis 26, a globular star cluster located about 23,000 light-years away. Many thousands of stars gleam brightly against the black backdrop of the image, with some brighter red and blue stars located along the ou.....»»
Comcast’s new remote control was designed for—and with—disabled users
