Abstract : As a part of a continuing program of laser efficiency improvement studies, a preliminary investigation has been made of the feasibility of converting the energy from an essentially white light source into useful pumping wavelengths by means of fluorescence. Both fluorescent dye solutions and powdered phosphors have been considered, and a laser head of coaxial design has been constructed that will enable an experimental study to be made of the use of either, or a combination of both, in modifying the light from an electronic discharge tube. Geometrical design of the optical coupling between lamp and laser rod also comes under study in the search for the ultimate design for the maximum conversion of electrical energy input into coherent light output.
