Antimatter Molecule Should Boost Laser Power

Laser Lover writes "Molecules made by combining an electron with their anti-particle positron have been created by researchers at the University of California Riverside. The team's long term goal is to use the exotic material to create 'an annihilation gamma ray laser', potentially one million times more powerful than existing lasers. 'An electron can hook up with its antiparticle, the positron, to form a hydrogen-like atom called positronium (Ps). It survives for less than 150 nanoseconds before it is annihilated in a puff of gamma radiation. It was known that two positronium atoms should be able to bind together to form a molecule ... '"

Because that's what they were saying the first time this was posted.

Burning your gamma ray candle in both ends

[viking80]

To conserve momentum (and other) at least two photons are released in opposite direction when the two particles annihilate each other. If this is part of a gamma ray laser, you will have two rays: One aimed at your enemy, one in your face, and a mirror will probably not work at 0.5MeV.

Positrons aren't actually that hard to find. All you need is (trying to remember Chem 2) an isotope that produces beta+ radiation. Heard of a PET scan? The P is for Positron. They put some radioactive sugar in your brain and map where the annihilations occur to determine brain activity.

To crush our enemies, see them driven before us, and hear the lamentations of their women.

The only real way to win a war millitarily then, is to totally annihillate the enemy. And that is no longer an option when you can't tell for sure who is your enemy and who isn't. And the fact that you kill a million people creates new enemies.
