Abstract:

Experiments were performed to detect LASER oscillations at 3 microns and at 7 microns from cesium vapor optically pumped with light from helium discharge lamps. No oscillations were observed. Fluorescence measurements have led to the construction of an improved system. Work was carried out on several possible LASER media utilizing collisions of the second kind in a gas discharge. Studies of the spacial and temporal behavior of the ruby R line LASER was investigated and crystal boules of calcium tungstate containing various concentrations of rare-earth ions were grown. Oscillation was attempted, unsuccessfully in each of these schemes. Studies of crystal perfection indicate that the internal quality of these crystals is not yet adequate. Two new forms of the Fabry-Perot interferometer have been constructed, which are superior in adjustment tolerances. Several aspects of the optical behavior of Fabry-Perot interferometers which are of importance for the understanding of F. P. LASERs have been studied theoretically.
