Applied Physics Letters. 10:160-162
Laser activity has been obtained from terbium tris (1, 1, 1‐trifluoroacetylacetonate) at room temperature in a liquid solution in acetonitrile and in p‐dioxane. Threshold pumping energy is about 1700 J. Characteristic line narrowing, spiking and

1976 International Conference on Submillimeter Waves and Their Applications.
The low spectral emission of black bodies in the FIR and the heretofore unavailability of oscillators or other active networks has resulted in very little knowledge of atmospheric characteristics. This paper describes the beginning of a program for t
