    Abstract: This application disclosed light polarizing apparatus in which light traverses a light path more than once. The light path passes through an amplification region caused by a population inversion. An optical element is mounted to intersect the light path at Brewster's angle polarizing the light passing therethrough.

    Abstract: Method and tool for fracturing the cement interface between a crown and a tooth or the like. The method is accomplished by positioning a piezoelectric driven rapid impacting tool against one side of a portion of a crown covering the tooth. The tool is covered with a malleable metal and is interfacing abutment with said crown. The opposite side of the crown is abutted against an anvil which is covered with a thicker malleable metal interface.

    Abstract: Optically pumped laser amplifiers are disclosed. One type of such amplifier utilizes an excitable medium, the atoms, ions or molecules of said medium having well defined energy states including a lowest state, a lower state above said lowest state, and a higher state above said lower state, and a bright pumping light source composed of a radiative substance different from such medium which radiative substance emits energy in a spectral range which can be absorbed by such medium, and wherein the major portion of the energy absorbed by such medium causes transitions of the atoms, ions, or molecules thereof to populate the higher state. Another type of such amplifier utilizes a medium of atoms, ions, or molecules, some of which have broad bands of energy levels corresponding to a broad band of absorption transitions and energy levels corresponding to at least one fluorescent emission transition, the upper energy levels of said broad bands being above the upper level of said fluorescent emission transition, and wherein some of the upper energy levels above the upper level of said fluorescent emission transition are rapidly quenched via non-radiating transitions to the upper level of said fluorescent emission transition. In a preferred embodiment of the latter amplifier, the lower energy level corresponding to the fluorescent emission transition is relaxed by non-radiating transitions.

    Abstract: A fiber optic energy sensor and optical demodulation system is disclosed wherein the signal energy to be sensed or detected causes an etched single mode fiber to be stretched or compressed which causes the optical path length for electro-magnetic radiation traveling in the core of the optic fiber to change. The change in optic path length modulates the electro-magnetic radiation traveling in the fiber.
