Description: 

Caption reads: "Spectrum Gap-Filler - a laser-pumped maser which in principle provides the technique to invade the vast unprobed 'gap' of the electromagnetic radiation spectrum has been developed and successfully demonstrated by scientists at Hughes Aircraft Company's research laboratories. The laser-maser technique, which lays open broad areas of communication between radio and light frequencies previously unassailable, provides a new tool for outer-space communication and for probing secrets of matter. Hughes scientist Irnee J. D'Haenens adjusts lens which focuses the coherent optical radiation from a ruby laser (in glass at center) onto the maser ruby crystal (between magnets at right), early 1960s."
