Attached image from Elbit's investors conference showing laser modules developed for helicopters (STING HEL) and fixed wing aircraft (XCALIBUR HEL).

In the context of Israel's HEL development, Rafael is a prime contractor for ground based solutions, and Elbit is a prime for aerial solutions.

Pentagon’s Megawatt Laser Demo To Highlight Recent Tech Breakthroughs​

Pentagon’s Megawatt Laser Demo To Highlight Recent Tech Breakthroughs | Aviation Week Network

As high-energy lasers become weapons for countering small drones, the technology is on its way to demonstrating the potential to shoot down strategic threats.

nLight megawatt demonstration scheduled for this year

Demonstrate a 1-megawatt-class laser made by nLight, which is capable of shooting down ballistic and hypersonic missiles.

Directed Energy — nLIGHT — nLIGHT

nLIGHT’s high-power directed energy lasers enable next-generation layered land and sea defenses that complement traditional kinetic defenses by offering a deep magazine, low cost per engagement, and speed-of-light delivery to defeat wide range of targets, including drones, rockets, artillery, mortar

In addition to scaling to 1 MW this laser will develop advanced adaptive optics for atmospheric correction.

Looking at the size of the spot on target (half radius, quarter area), the nLight 1MW laser could be 8x more effective than the 500kW LM laser.

It’s unclear from the CRS report why the Army chose to abandon IFPC-HEL. However, the decision mirrors its earlier move to drop the Stryker-mounted 50 kW Directed Energy Maneuver-Short Range Air Defense (DE M-SHORAD) laser weapon in favor of the upcoming Enduring High Energy Laser system, which may become the service’s first official directed energy program of record.

You know the planet is in a mess when reporters covering high energy physics sound like TMZ nightcrawlers or war correspondents:

I still haven't recovered... it's quantum day, so..."commence to jiggling" BUT THEN, this awful laser strike...I'm never going to twerk again... these guilty buns have got no rhythm....I'm going somewhere safe...like Mumbai

Any color you like

Flat optics
A collaborative research group has developed a fully automated roll-to-roll manufacturing platform capable of producing large-area visible metalenses at a rate of 300 units per second, marking a major breakthrough in translating metasurface technology from the laboratory to real-world industrial deployment.

For glasses
Researchers at The University of Osaka, in collaboration with ULVAC, Inc. and Ritsumeikan University, have developed a new LED structure that generates circularly polarized light from a single chip.

X-rays
In the Journal of Astronomical Telescopes, Instruments, and Systems, researchers recently addressed this challenge by developing a practical method to align lobster-eye X-ray optics for space telescopes. The team led by Hatsune Goto from Kanazawa University, Japan, designed and tested an alignment strategy for EAGLE, the wide-field X-ray monitor planned for the HiZ-GUNDAM mission.

EAGLE uses devices called Micro Pore Optics (MPOs), which are thin glass plates with microscopic channels. When X-rays enter at a shallow angle, they reflect off the channel walls and focus onto a detector, forming a distinctive cross-shaped image. The position of that cross tells astronomers where in the sky the X-rays came from.

Egyptian mummy remains were examined at Semmelweis University's Medical Imaging Center (OKK). The archaeological finds arriving from the Semmelweis Museum of Medical History, Hungarian National Museum Public Collection Center (MNMKK) were analyzed using the institution's newest CT scanner equipped with a photon-counting detector. Thanks to state-of-the-art imaging technology, highly detailed images have been captured that were previously unavailable, and the initial results promise significant scientific advances.
