Ultra-fast laser has helped to change the properties of solid materials
Scientists have used photoelectron spectroscopy with angular and temporal resolution for the direct measurement of ultrafast electron self-energy changes during irradiation of high-temperature superconductors based on cuprates.

Normal laser stimulates emission of radiation by the transfer of electrons being in the working chamber to the excited state, and when they reach a high enough energy, they can give up a part of it by emitting photons. It was they who form a coherent beam of light that we call laser radiation.

The companies Lockheed Martin and DRS Technologies received $ 4.4 and $ 3.2 million for the development of a laser radar (lidar):  an emitter with the ability to change parameters of the signal and the corresponding detector. Earlier $ 3.1 million were received by Princeton Lightwave laboratory

Until recently, record density in this configuration was limited by the size of the focal spot of the laser. Scientists from Seagate Technology proposed the use the optical nanoantenna for the concentration of electromagnetic radiation. Data density on magnetic disks doubled every three years since their invention in 1955.

The Soviet device "Lunokhod-1" was brought to the surface of the Earth satellite by automatic interplanetary station "Luna-17" in 1970. The last time he got in touch with the Earth on the radio was in 1971. "Lunokhod-1" was equipped with a reflector. With their help scientists detect the exact distance from the Earth to the Moon (a laser beam traveling at the speed of light is sent to the reflector, and the researchers detect how long it took to go from our planet to the satellite and back). After communication with the Lunokhod was lost, the researchers could not "catch" the reflector, as they did not know the exact location of the device. In mid-March 2010 American orbital sonde Lunar Reconnaissance Orbiter (LRO) transmitted the photos to the Earth, with "Lunokhod-1".
