C. K. N. Patel, Bell Telephone Laboratories, Murray Hill, New Jersey; Physical Review 136, A1187–A1193, 30 November 1964; DOI 10.1103/PhysRev.136.A1187. Primary abstract: continuous-wave and pulsed-discharge laser action on rotational transitions of CO2 vibrational bands; strongest reported line 10.6324 micrometres in vacuum and continuous output about 1 mW. The abstract also reports time-dependent pulsed excitation. The initial-only published byline is retained; no full-name guess is made.
