Building gamma-ray lasers powered by an exotic hybrid of matter and antimatter may sound like science fiction, but scientists are now a step closer to doing it. Whereas the wavelengths of traditional ...

A new way of creating femtosecond, quasi-monoenergetic gamma-ray pulses has been proposed by Serge Kalmykov at the University of Nebraska-Lincoln and colleagues. Their scheme involves using a stack of ...

In principle, positronium could be used to make a gamma ray laser. It would produce a highly energetic beam of extremely short wavelength that could probe tiny structures including the atomic nucleus ...

In the dark and distant past, I called myself a laser physicist. I would speak with pride of lasers that produced incredible power: the thought of a petawatt laser system would bring a tear to my ...

The goal of the work reported here is the perfection of a powerful laser based on the coherent annihilation of a Bose-Einstein condensate of positronium, the hydrogen-like atoms formed from bound ...

Laser focused: simulation of gamma rays being produced by accelerated electrons. (Courtesy: D J Stark et al./Physical Review Letters) A collimated beam of gamma-ray photons could be created by firing ...

Muons are elementary particles that resemble electrons, but they are heavier and decay very rapidly (i.e., in just a few microseconds). Studying muons can help to test and refine the standard of ...

This article was originally published on The Conversation. Read the original article. Gamma ray bursts, intense explosions of light, are the brightest events ever observed in the universe—lasting no ...

Practical laser weapons came another step closer to reality recently as defense contractor Northrop Grumman tested the latest version of its Firestrike solid-state lasers. On May 1st, the company ...

A scientist in California has taken steps toward a long-sought gamma ray laser by harnessing positronium bubbles in special liquid helium. Positronium is a volatile, short-lived atom that seems kind ...
