摘要： A white light source is described in which a trivalent metallic ultraphosphate is irradiated with a low voltage electron beam. The metallic ions are generally restricted to the lanthanide rare earth ions and yttrium. The material so irradiated emits light in a spectral continuum centered in the visible portion of the electro-magnetic spectrum. This emission is, however, in addition to any narrow bandwidth light emission of the type generally associated with a transition of the metallic ion involving the electrons of the 4f shell.

摘要： A optical logic device is described in which binary logic functions are accomplished by use of a laser, such as a dye laser, whose output has a polarization direction which is determinable by the direction of polarization of an input excitation laser pumping pulse. An optical component, such as a birefringent element, establishes a pair of bistable polarization directions representative of the binary logic levels. Bistable polarization operation is achieved by requiring a greater intensity of an input laser pumping signal to establish one polarization direction when compared with the input intensity required to establish the other polarization direction. A Brewster plate may be employed to establish the bistable operation of the laser medium.

摘要： A photochromic plastic has been discovered which is useful in the manufacture of protective eyeglasses. The photochromic plastic comprises a host polymer material and a dopant. The plastic exhibits photochromic properties due to excited state absorption which occurs when the material is exposed to UV light. The eyeglasses function as protection against radiation from the sun as well as from industrial and other sources. The dynamic range and response time of this novel photochromic plastic may be tailored in accordance with the particular use or application desired.

摘要： Apparatus employing a light beam to affect another light beam. A primary beam of linearly polarized monochromatic light is directed on an element of chromium chalcogenide spinel magnetic semiconductor, specifically single crystal CdCr.sub.2 Se.sub.4. A control beam of monochromatic light is selectively elliptically polarized and directed at the element. As the light beams traverse the same path through the element the circularly polarized control beam interacts with the element thereby changing the effect of the element on the linearly polarized primary beam to rotate the plane of linear polarization of the primary beam. A linear polarization analyzer receives the primary beam from the element and passes, blocks, or diverts light depending upon the plane of linear polarization of the incident light.
