Description

In THE PHYSICAL REVIEW, Vol. 136, No. 5A, Nov. 30, 1964, pp. 1187-1193, the entire issue in original printed wrappers. A very good copy, ownership inscription, spine discolored. FIRST EDITION OF THE FIRST REPORT OF CONTINUOUS LASER ACTION IN PURE CARBON DIOXIDE. " Patel joined Bell Laboratories in 1961, and subsequently became Executive Director of the Research, Materials Science, Engineering and Academic Affairs Division at AT&T Bell Laboratories in Murray Hill, New Jersey, where he developed the carbon dioxide laser. Patel's discovery, in 1963, of the laser action on the vibrational-rotational transitions of carbon dioxide and his discovery, in 1964, of efficient vibrational energy transfer between molecules, led to a series of experiments which demonstrated that the carbon dioxide laser was capable of very high continuous-wave and pulsed power output at very high conversion efficiencies."
