WASHINGTON (Reuters) - The sun may offer
a cheaper alternative to traditional medical lasers, Israeli researchers said
Solar-powered lasers can kill tissues as well as medical lasers, but at a
lower cost, said Jeffrey Gordon, a researcher at Ben-Gurion University in Negev,
Israel, who led the study.
That could make the lasers affordable for hospitals that cannot buy
traditional medical lasers, which concentrate electricity, he said.
There are limits, Gordon said in a telephone interview.
