Laser Technology and Its Applications

David Kaplan explores the use of military-grade lasers at the Redstone Test Center in Alabama. The laser, named Zeus, is used to destroy mines and bombs by transferring heat to explosive devices until they detonate. The video also discusses the potential of using lasers for spacecraft propulsion, where a laser beam could propel a spacecraft by heating material at its back, effectively turning lasers into interplanetary gas stations. This technology could enable precise and powerful propulsion from a remote location, pushing spacecraft to the farthest reaches of the solar system.
