What kind of light has laser-like properties but is not a laser?

This thing is possible, but he has not been popularized belong to the new technology, the following is the introduction, but you want to find a laser alternative is very difficult Traditional medical laser equipment is expensive and requires electric power, Israeli researchers have announced, in fact, solar energy lasers are a very good "alternative". Jeffrey Gordon from Ben-Gurion University in Israel and his colleagues in the latest issue of the U.S. "Applied Physics Letters," said in killing cancerous tissues, solar lasers and medical lasers are equally effective, but at a much lower cost. The researchers said the solar laser system relies on a collector outside the laboratory window to "collect" sunlight, which is transmitted to a small plane mirror above the reflector after the mirror concentrates light, and then the solar energy is transmitted into the laboratory floor using optical fibers. Experiments with chicken and rat livers have shown that solar lasers can produce the same therapeutic effects as medical lasers. However, Gordon also pointed out that solar lasers also have limitations, "the use of the location must be in areas with sufficient sunlight, and the use of time only in the sun is more abundant for a few hours." It is reported that if this solar laser device has the ability to produce large quantities, the price of each unit is about 1,000 U.S. dollars, while the traditional medical laser equipment in the 150,000 U.S. dollars per unit.
