Trotter is chairman oi Lhci board of General Telephone and Electronic: Laboratories, Inc. In the demonstration, Trotter used a heliumencon laser in| which the electrons of the hel' um atoms are excited by a light' beam. when these electrons re- turn to a lower energy level they giro up quanta of energy, whioii in turn stimulate the‘ electrons or the neon atoms to higher energy levels When these electrons fall back, they> give off quanta or light which' are in phase and therciore at higher intensity than the source The parallel laser rays are capable ot producing beams oi highly concentrated l i g h t which can be used in medical work. The laser is presently used in retinal surgery and i for the treatment oi certain skin ailments. To illustrate the use of the laser in communications, Trot»: ter broadcast a tape recording: on a laser beam to a receiver- and ainpiiiier. When the laser beam was blocked. the anipir fier received no signals and the sound stopped. Trotter explained that to have intelligence superimposed on a beam, the light must be order- ed; the laser produces a con lherent, ordered beam. Furthe..t since the amount of information‘ a beam can carry varies r'ircet- iy with the lrequcncy o: the, radiation, the laser beam hasl ltiwa Thihléis l Decide on Cole for Secretary .
