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

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.

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.

Click to expand...
These palletized lasers in a box are designed to operate in the real world, not in a cheesy sci-fi show. Palletized laser weapon systems in a box are designed to provide a rapidly deployable, modular, and cost-effective defense against the proliferation of low-cost threats. The palletized box approach allows these systems to be transported easily and mounted on various platforms—including pickup trucks, trailers, ships or fixed sites—offering a "plug-and-play" capability for immediate, on-site protection of critical infrastructure and personnel. They allow military units to move, install, and operate laser defense in varied, austere environments.

Although it would be cool if the laser weapons were more sci-fi looking, it is more important in the real world that they be deployable, integratable, reliable, maintainable, manufacturable, robust and cost-effective, all of which are provided by the palletized box design.
 
The wording there makes you think of a weapon strike---that was a lasercomm achievement.

In directed energy advances...

Could that be combined with other tech?

I hate the clickbait title and hyperbolic language of the article, but if you look passed that BS, the Chinese did accomplish an impressive engineering demonstration that brought together well-known technologies and techniques in the fields of optical communications and atmospheric propagation of lasers.

I doubt that the plasma-based particle accelerators and relativistic mirror technology could be combined with Bose Einstein Condensate (BEC) atom lasers because the former relies on the interaction of charged particles and electromagnetic waves, and the latter requires neutral atoms because BECs require neutral, ultracold bosons that occupy the same lowest quantum state. BECs cannot be formed using charged atoms, i.e., ions, since they repel one another, making collections of ions difficult to cool to the ultracold temperatures required for BECs.

A possible work around, would be the use of ions embedded in a BEC that form "molecular ions" as discussed in the article at the following link: https://physics.aps.org/story/v10/st8 This was theoretical work in 2002. A Google search indicates that formation of molecular ions in a BEC have been experimentally verified since then. However, the interaction of the molecular ions in the BEC with electromagnetic waves has been used to separate the ions from the neutral BEC atoms rather than accelerate the BEC along with the molecular ions.

As to the Star Wars Death Star beam combining, that concept is already being used in modern laser weapons. The Death Star weapon is termed a "composite beam superlaser," which converges multiple laser beams into one. In modern optical fiber based laser weapons, the laser beams from lower power fiber lasers are combined into a single high power laser output. Two main methods of laser beam combining are used. Some weapons use spectral beam combining, which combines lasers at slightly different wavelengths into a single beam. Some weapons use coherent beam combining, which synchronizes the optical phases of several fiber laser emitters at the same wavelength so that their combined beams behave as a single, more powerful coherent laser beam.
 
The fibers are akin to rail-lines.

I seem to remember...I don't know if it was a BEC, but something that could delay a beam, then release it. Above I linked to an 8 hour firing.

I am trying to rack my brain as to how that output over time could be compacted somehow....a caseless round... something..that is to lasers what a dewar is to nukes.

Bose-Einstein condensates (BECs) are used to dramatically slow light to bicycle speeds (approx. 17 m/s) or stop it entirely by manipulating atomic energy states in ultracold, quantum-degenerate gas, typically of rubidium or sodium atoms. Pioneered by Dr. Lene Hau in 1999–2001, this technique employs Electromagnetically Induced Transparency (EIT) to render the opaque medium transparent, allowing a light pulse to be compressed and stored in the atomic spin states of the BEC, and later released intact.

When the light pulse enters the dense BEC medium, it is compressed from roughly 1 to 2 miles in length down to less than 0.001 micron.

Light storage in a BEC for up to about a second has been demonstrated, but with storage time dependent losses in energy and fidelity. See https://journals.aps.org/prl/abstract/10.1103/PhysRevLett.103.233602

See https://www.spie.org/news/behind-th...speed of light,the speed of light in a vacuum. and https://www.facebook.com/groups/930540941927100/posts/1249151793399345/ and

In response to your statement "The fibers are akin to rail-lines" I point out that in modern fiber-based laser weapons, the beam combining that creates the high-power output beam occurs outside of the fibers in free space. While the amplification of the laser light happens inside specialized optical fibers, the final combination of these individual beams into a single high-power beam requires external optics and beam paths because the final power/energy if confined to the size of a fiber would be far above the thresholds of nonlinear optical losses and damage in a fiber, which is why the weapon requires using multiple lower power fiber lasers instead of single high power fiber laser in the first place.
