Decades of Discoveries Broadened the Laser Spectrum

5 days ago | photonics.com | Jeff Hecht

Visible lasers debuted with just a couple of shades of red. A series of advancements has grown over the years into a cascade, yielding an amazing range of colors to feed innovation. At the dawn of the laser age, any color could be attained from a laser, as long as it was red. Theodore Maiman’s first laser was a ruby rod that emitted pulses at 694 nm, the long end of the visible spectrum.

Oldest and Largest Impact Crater Found on Venus

Nov 6, 2024 | skyandtelescope.org | Jeff Hecht

Scientists have found possibly the oldest and largest crater on Venus — and it’s like none they’ve ever seen on our sister planet. Detailed mapping of one of the oldest terrains on Venus has revealed a giant impact structure of a type never before seen on any terrestrial planet. Oddly, the keys to understanding it came from studying craters on two icy moons of Jupiter. Venus is the least understood of the rocky planets because its thick atmosphere obscuring its surface.
Michael A. Johnson: Preventing optical damage at the National Ignition Facility

Oct 31, 2024 | spie.org | Jeff Hecht

The National Ignition Facility (NIF) was in trouble a dozen years ago. The Lawrence Livermore National Laboratory (LLNL) wanted the giant laser to show the feasibility of igniting a fusion chain reaction by heating and compressing tiny pellets of hydrogen fuel. The laser had reached the 1.8 megajoules (MJ) lab researchers expected would be needed, but the fusion yield was far short of ignition, the point where the fusion yield exceeded the energy delivered to the fuel pellet.
We’ve Found the Source of Most Meteorites

Oct 21, 2024 | skyandtelescope.org | Jeff Hecht

Scientists have traced 70% of meteorite falls to three collisions that occurred in the asteroid belt within the past 40 million years. At last, we know where most meteorites come from. Two studies published in Nature have traced 70% of meteorite falls to three collisions in the asteroid belt that occurred within the past 40 million years. Previously, scientists had only identified the origins of 6% of meteorite falls: the Moon, Mars, and the asteroid 4 Vesta.
Did a Ring of Rocks and Dust Orbit Earth Before the Dinosaurs Roamed?

Sep 23, 2024 | skyandtelescope.org | Jeff Hecht

A team of scientists thinks a clustering of ancient impact craters points to a temporary ring around Earth hundreds of millions of years ago. Earth's gravity might have snared an asteroid making a very near miss of the planet 466 million years ago. As it shattered its debris went into orbit, giving our planet its own ring that may have lasted millions of years. Astronomers have long thought that Earth was too small to have rings like the giant planets do.

D’Haenens famously referred to the first ruby laser—partly in jest—as “a solution looking for a problem.” [HRL Laboratories, courtesy of AIP Emilio Segrè Visual Archives] While some initially wondered about practical applications for the laser—an invention born out of basic research—within a few decades after its first appearance, it was offering solutions from high-speed printing to crystal-clear music.
