Abstract
Methods are disclosed for operating a laser. Such methods may comprise operating the laser to emit electromagnetic energy in an infrared range in pulses with a pulse duration of greater than 1 ns. The wavelength of infrared electromagnetic energy may be in a range of about 2.6μ to about 3.3μ or about 1.8μ to about 2.1μ. The pulses may have a pulse energy selected to deliver an energy density of 2,500 J/cmor greater. The laser electromagnetic energy may be delivered for a medical application, such as cataract surgery to break apart a cataractous lens by photodisruption.
