Scientists and engineers at Yale University have just created an anti - laser , a equipment which immerse light . Instead of shooting zip out of a vacuum tube , it takes energy into a thermionic vacuum tube . or else of creating light , it create darkness . How does it go ?
optical maser lead off out in a tube that is mirrored on both sides . When DOE is forced into the tube , the material within gets activated . The electrons in the atoms of the cloth jump up a level , and then decrease back down . When they do , they utter a photon , which starts traveling around the pipe . It bounces off the mirrors on both side , getting in phase with all the other protons in the tube . by and large , the mirror on one side of the subway is only half - silvered , so eventually the photons find an opening and march out in a directional , single - wavelength shaft of light .
