    Abstract: An advanced communications system comprising an emitter and an improved receiver (detector) utilizing modulated beams of neutrino and antineutrino waves as information carriers between the emitter and the receiver. Generation of modulated neutrino and antineutrino beams in the emitter is achieved by a laser-like medium, while detection and demodulation of the neutrino and antineutrino beams is accomplished by a second laser-like medium which registers the flux (or fluence) of modulated neutrinos and antineutrinos passing there-through by means of resonant stimulated deexcitation of lasable excited states. In addition to the information transmission utilization, the neutrino emitter and receiver (detector) system may also be employed to gather information by the probing of internal earth structures. Such structures cause measurable refractions and retardations of the propagated pulses of monochromatic coherent neutrino waves traveling through the earth between the emitter and receiver (detector), at certain predetermined neutrino frequencies.

    Abstract: In a disclosed embodiment, an ultra-cold-matter (UCM) system includes a source cell nested within a hermetically-sealed ultra-high-vacuum (UHV) enclosure. Source particles, e.g., strontium atoms, can be generated within the source cell by heating a non-vapor-phase source material. The source cell is thermally isolated, e.g., by UHV, from the enclosure. Accordingly, heat is retained in the source cell, reducing the amount of heat that must be generated in the source cell to generate the vapor-phase source particles. Particles can exit the source cell to an UHV ultra-cold region where the source particles can be cooled to produce ultra-cold particles thermally isolated from the heat within the source cell.

    Abstract: Experimental studies of single molecule mechanics require high force sensitivity and low drift, which can be achieved with optical tweezers through an optical tweezers apparatus for force measurements. A CW infrared laser beam is split by polarization and focused by a high numerical aperture objective to create two traps. The same laser is used to form both traps and to measure the force by back focal plane interferometry. Although the two beams entering the microscope are designed to exhibit orthogonal polarization, interference and a significant parasitic force signal occur. Comparing the experimental results with a ray optics model, the interference patterns are caused by the rotation of polarization on microscope lens surfaces and slides. Two methods for reducing the crosstalk are directed to polarization rectification by passing through the microscope twice and frequency shifting of one of the split laser beams.

    Abstract: An optical arrangement has a laser configured to emit a laser beam, an amplitude mask and a focusing element. The amplitude mask is disposed between the laser and the focusing element in a path of the laser beam such that the laser beam hits the amplitude mask before being modified by the focusing element so as to direct the laser beam to a focal point within a photosensitive material.
