ExtremeTech has an article suggesting the International Space Station may add a Laser "CAN-non" in coming years.
The business end of the proposed laser system would be a Coherent Amplification Network (CAN) laser that can focus a single powerful beam on a piece of debris. The laser would vaporize the surface of the target, causing a plume of plasma to push the object away from the station and toward the atmosphere.
This is still just a proposal, but a test version of the laser might be deployed to the station in a few years.
The Extreme Universe Space Observatory (EUSO) is scheduled to be installed on Japan's ISS module in 2017. This is not by design a space-junk-killing piece of equipment. It's intended to monitor the atmosphere for ultraviolet emissions caused by cosmic rays.
However it might serve as an experimental platform for testing (at much lower power) the capability of slight deflections of orbiting space junk.
We discussed the general problem of space junk here on Soylent News at the beginning of the month.

You merely try to get it to thrust against the direction of travel.
Orbital mechanics will handle the rest.
No, you are mistaken. I've always had this sig.

Ahh yes, you are absolutely correct, It is all a matter of velocity, not direction. I should know better.
Though I wonder how this lets you deal with debris if you are the one catching up to the debris when it crosses your orbit. I suppose in that situation the space station or craft with the laser also has it's own propulsion and would perform a maneuver to avoid. Once it passes the debris by, it can pew pew it with the laser to get the debris to deorbit.
