“…Parametric amplifiers yield noise temperatures around 150 o:K up to 40 GHz and about half this with cooling. Cooling has been provided by liquid nitrogen [Uenohara et al, 1963;Uenohara and Elward, 1964] and by closed-cycle refrigeration [Rucker, Morrow, and Grimes, 1965]. Feri-imagnetic tuning of parametric amplifiers was demonstrated by Kotzebue [1965j.…”

The generation of new laser devices, techniques, ideas, and applications continued at an unslowing pace during 1963–1966. While no large‐scale or commercially important laser applications have yet emerged, lasers have found innumerable and often irreplaceable applications both in science and in technology. Increasing numbers of useful commercial applications are slowly beginning to emerge at the end of the period.

“…Early interest focused on telecommunications [13][14][15] and radio astronomy [16,17]. However, despite efforts to increase operating frequencies and bandwidth, the parametric amplifier was displaced by the travelling wave tube.…”
