To create a gamma-ray laser beam, positronium needs to be in a state called a Bose-Einstein condensate—a collection of positronium atoms in the same quantum state, allowing for more interactions and gamma radiation. Such a condensate is the key ingredient of a gamma-ray laser.Dec 6, 2019

Are gamma-ray lasers possible?

A gamma-ray laser, or graser, is a hypothetical device that would produce coherent gamma rays, just as an ordinary laser produces coherent rays of visible light. In his 2003 Nobel lecture, Vitaly Ginzburg cited the gamma-ray laser as one of the thirty most important problems in physics.

Is a gamma-ray weapon possible?

American military scientists are developing a weapon which kills by delivering an enormous burst of high-energy gamma rays, it is claimed today. The bomb, which produces little fallout, blurs the distinction between conventional and nuclear weapons, and experts have already warned it could spark a new arms race.

What’s the most powerful laser?

Magurele Laser in Romania officially becomes the most powerful laser in the world. The laser at Magurele, near Bucharest, Romania marked a world premiere after reaching the highest power, 10 PetaWats.

Which laser has the highest frequency?

The wikipedia page for gamma-ray lasers certainly makes them sound like a difficult research project, not something in production. The graphic they have for commercial lasers by frequency seems to imply the highest-freq commercially available laser is pretty solidly ultraviolet.

What is a gamma-ray bomb?

Gamma-ray bursts (GRBs) are short-lived bursts of gamma-ray light, the most energetic form of light. Lasting anywhere from a few milliseconds to several minutes, GRBs shine hundreds of times brighter than a typical supernova and about a million trillion times as bright as the Sun.

Can a laser cut a human?

Unlike other ordinary light sources, laser cutting lasers can achieve energy concentration due to their monochromaticity, coherence, collimation and high energy density, thus causing damage to human organs (especially human eyes). .

Can laser reach moon?

The typical red laser pointer is about 5 milliwatts, and a good one has a tight enough beam to actually hit the Moon—though it'd be spread out over a large fraction of the surface when it got there. The atmosphere would distort the beam a bit, and absorb some of it, but most of the light would make it.

What are the 3 types of laser?

Types of lasers

• Solid-state laser.
• Gas laser.
• Liquid laser.
• Semiconductor laser.

What is a Class 4 laser?

Class 4 is the highest class in terms of laser hazards. If you're within the hazard zone, you're exposed to severe eye and skin injuries. In addition, combustible materials shouldn't be in the laser's surroundings to avoid fire hazards. Diffuse reflections of class 4 lasers are also hazardous.
