Optically pumped laser action has been observed in dideuteroacetylene. A total of fifteen output wavelengths in the 17.4 to 20.5 μm region are produced, pumped by seven CO 2 laser lines. The laser shows a number of unusual features, in particular pu

The collisions of thermal energy electrons which cause de-excitation of excited states of some metal ions are studied experimentally using flowing afterglow techniques. For all levels whose calculated radiative lifetimes exceed 100 ns, the effects of

Superfluorescent emission from carbon tetrafluoride was generated by a single-mode CO2 TEA laser whose frequency was swept over 30 MHz of the 9R(12) laser line centre. The results confirm the spectroscopic identification of the CF4 pump transition wh

A study of superfluorescent emission from CO 2 laser-pumped CF 4 has revealed effects of anomalous dispersion giving rise to large reductions in the group velocity of the superfluorescence. Strong gain modulation of this superfluorescence is reported

Flowing afterglow techniques are employed for the study of the thermal energy reactions of He+ with Zn, Cd, and Se, and of Ne+ with Mg. The He+ reactions have a practical importance as excitation mechanisms in the He-Zn; He-Cd and He-Se laser systems

The processes which excite and de-excite levels of the zinc ion in a helium afterglow containing zinc vapour are studied using a flowing afterglow technique. It is shown that thermal energy charge transfer reactions between atomic helium ions and gro

The reactions which pump the upper laser levels of the He-Cd and He- Zn lasers are investigated by means of a study of excitation during thermal energy charge transfer and Penning reactions in a flowing afterglow of helium. Measurements of emission l
