Most lasers are made up of silicon wafers using expensive processes, similar to the ones used to make microprocessors. Scientists have designed a new way to print a type of organic laser onto any surface, using technology similar to the one found in many homes.
Scientists have been able to generate the world’s fastest laser pulse with a beam shot for 67 attoseconds (0.000000000000000067 seconds). This breaks the previous record of 80 attoseconds that was established in 2008. This could help engineers see extremely rapid quantum mechanical processes, like the movements of electrons during chemical reactions.
The Laser Relativity Satellite (LARES) will allow Italian astrophysicists to measure the frame-dragging effect of general relativity up to an accuracy of 1%. Laser ranging stations on Earth will fire lasers at LARES to calculate its distance and orbit, with a high degree of precision.
