These devices were used to cool aclump of rubidium atoms to create the first (*) Bose-Einstein condensate, and they are also used todeliver power to a deuterium-tritium pellet in inertial confinement fusion.
One type of this device contains a series of magnets with alternating poles called an undulator,and uses charged particles moving sinusoidally as the medium. These devices were used to cool aclump of rubidium atoms to create the first (*) Bose-Einstein condensate, and they are also used todeliver power to a deuterium-tritium pellet in inertial confinement fusion. These devices require athree-level system, because they rely on population inversion, and simple ones consist of a gain mediumwith a pair of mirrors on either side to create a resonator. For 10 points, name these devices which usechanges of energy levels in electrons to generate a coherent beam of light, used in CD players, weaponsights, and pointers
