	ScienceDaily: Scientists Succeed In Cooling Solid Material With Laser
		Science Daily — A team of researchers at the University of the Basque Country (UPV/EHU) have experimentally demonstrated something that other scientists have been trying to achieve for decades: the cooling of erbium-doped materials with laser light.
		These devices would function by means of dual laser pumping in which the light wavelengths would be used for the laser pumping and the other wavelength (close to the previous one) to produce optical cooling that would counteract the heating produced by the laser action.
		Laser Trapping Of Erbium May Lead To Novel Devices (April 30, 2006) -- Physicists at the National Institute of Standards and Technology (NIST) have used lasers to cool and trap erbium atoms, a "rare earth" heavy metal with unusual optical, electronic and magnetic...

	Laser - Wikipedia, the free encyclopedia
		Many lasers are designed for a higher peak output with an extremely short pulse, and this requires different technology from a continuous wave (constant output) laser such as is used in communication, or cutting.
		However, fiber lasers do have a fundamental limitation: The intensity of the light in the fiber is so high that optical non linearities induced by the local electric field strength can become dominant and prevent laser operation and/or lead to the destruction of the entire fiber laser.
		Lasers used by hobbyists are generally class IIIa or IIIb lasers, although some have made their own class IV lasers.

		Lawrence Livermore laser technician Balbir Bhachu monitors the performance of the 13-kilowatt neodymium-doped glass version of the solid-state heat-capacity laser during a low-power test.
		Project manager Brent Dane, of Livermore’s Laser Science and Technology program, notes that the ultimate objective of the project is to build a next-generation system with enough electrical efficiency to produce a 100-kilowatt laser beam from the same 1 megawatt of input power.
		Although laser diodes are extremely efficient devices by ordinary laser standards—they typically convert 50 percent of their electric input power into light output—the remaining 50 percent of the input power shows up as high-intensity heat from a very compact source.
