The eurekalert link also seems to fail. Try

and find a press release for 6th March 2014 |
Hi Robert,
Thanks for the links.
They are broken because you have inadvertently prepended them with additional
http tokens.
The corrected links should be -
http://www.news.com.au/technology/sc...-1226848314008

The “trick” is to only displace the object by a tiny amount, thereby preventing a collision. This laser’s effect would be far too weak to rapidly affect the decay of the object’s orbit. To actually de-orbit a debris object with a laser requires forces about 1,000 times more powerful. To “ultimately de-orbit it entirely” would take about the same amount of time as if we had not illuminated it - this may well take decades, depending on the object.
