The most powerful lasers in the world can be used to make some of the most extreme conditions possible on earth, and are revolutionising science. Dr Kate Lancaster leads you through this extreme world with demonstrations along the way. http://bit.ly/RiSubscRibe When lasers were invented over half a century ago they were hailed as a “solution looking for a problem”. Since then lasers have come to revolutionise our lives through their practical applications such as data transport and CD/ DVD players, and as a tool for industry and science. The largest and most powerful lasers in the world can be used to make some of the most extreme conditions possible on earth. Scientists around the globe are using these lasers to try to miniaturise particle accelerators, make astrophysical conditions in the lab, and create fusion energy. Dr Kate Lancaster leads you through this extreme world with demonstrations along the way in celebration of the International Year of Light. Kate Lancaster was awarded a PhD in Advanced Fast Ignition studies (laser driven fusion) by Imperial College London before working at the Central Laser Facility at the Rutherford Appleton Laboratory. Her background is in laser plasma interactions and laser driven fusion and she is now the Plasma and Fusion industrial officer for the York Plasma Institute, University of York.
