Physicists build reversible tractor beam

[josephpalazzo]

Laser physicists have built a tractor beam that can repel and attract
objects, using a hollow laser beam that is bright around the edges and dark in
its centre.


It is the first long-distance optical tractor beam and moved particles one
fifth of a millimetre in diameter a distance of up to 20 centimetres, around 100
times further than previous experiments.


“Demonstration of a large scale laser beam like this is a kind of holy grail
for laser physicists,” said Professor Wieslaw Krolikowski, from the Research
School of Physics and Engineering.


The new technique is versatile because it requires only a single laser beam.
It could be used, for example, in controlling atmospheric pollution or for the
retrieval of tiny, delicate or dangerous particles for sampling.

Now all we need are shields and warp drive and teleportation.  :)

That is amazing.   I wonder how soon it will be used for sex?
