LASER & MASER, but is it possible to produce a "GASER"; Gamma-ray Amplification by Stimulated Emission of Radiation? I have never heard as a such device. Mayby it already exists?

It seems to be very dangerous, but also a tool in example sensitive surgerys.

Since there are x-ray lasers, I would think that in theory such a thing might be possible..

Getting those high energy photons to do what you want might be tricky.
I can't imagine a lasing medium that could produce a CW stream of gamma rays.
Much less in a pointer. But of course, my knowledge of physics is limited.

BTW, the first thing I read in the title was GAYSER. :D

X-ray laser:
World’s Most Intense X-Ray Laser Takes First Shots | Wired Science | Wired.com
World's First Hard X-ray Laser Achieves 'First Light'

It's a free-electron laser at 0.15nm!

Google is wonderful.

Not GAYSER... :)

But thanks for the links! I have done a X-ray scanning of my brain, but they didn't find anything. Or... of course they find something wich looked like a brain, but no illness!

..... I don't know why, but for some reasons, i don't think i can put it in any handheld host .....

Gamma rays and x-rays are the exact same thing. The only difference between the two names is the origin of the photons:

Gamma rays are emitted by the atomic nucleus
X-rays are produced by other means

So the question is difficult to answer: In theory it could exist, but that would mean powering the laser directly with a nuclear reaction. I don't see any feasible mechanism to get population inversion and stimulated emission from nuclei, except for a slight option using metastable isotopes.

I was under the impression that gamma rays are shorter wavelength radiation than x-rays. Common misunderstanding?

Thanks for the clarification. I'll have to do some more reading.

Its a very common misunderstanding, but also true for many practical applications. X-rays used to take pictures of the skeleton are generally much lower in energy than the photons produced in nuclear reactions.

There is, however, quite some overlap: The most energetic x-rays have more enery per photon than the weakest ones produced in nuclear reactions.

Back in the day when these terms were coined, there was very little overlap, and a distiction on energy could be made. The terminology changed to indicate the origin, as both are exactly the same EM radiation, with the exact same properties etc. Mistaking one for the other is of little consequences, and even many textbooks still cite the distinction in energy, though usually without a precise point where x-rays stop and gamma rays begin.

Obviously the same problem goes for the distinction between UV light and x-rays, but an arbitrary boundry as been defined at 10 nm to indicate the difference.

^ Good info! Now if I could just diy a UV/X-ray boundary hand held pointer.

The idea that the type of light be the first part of the acronym was done away witha long time ago. If it's microwaves, it's a maser. Anything above that is still called a laser.

BBC NEWS | Science/Nature | Mirror particles form new matter

they are currently making smth along those line...

the idea is simple, a black hole is technically a huge gamma ray laser gun. this is because of the constant annihilation of anti-matter around it.

scientist is trying to recreate this by using anti matter to generate this insanely high amount of gamma rays and turns it into a beam.
