Description: 

According to Steve Jacobs, this was probably the first photograph of a laser beam. (Phony as it was, it was better than a red spot on a screen) The experiment demonstrated for the first time that you could do with light what had been done previously at radio frequencies. It was demonstrated that you could get ideal signal-to-noise for optical communication by Laser Optical Heterodyne Detection. Photo appeared on the cover of Electronics, a McGraw-Hill Weekly on July 12, 1963.
