摘要： A spherical laser includes a transparent or semi-transparent outer spherical vessel having an internal cavity, an amplifying medium in the cavity, and means to excite the amplifying medium. The sphere is provided with a partially reflective coating to act as a spherical optical resonator. Excitation of the amplifying medium produces an optical gain. When the gain exceeds cavity losses and threshold conditions are met, lasing is supported. This creates a three-dimensional, spherically radiating emission, emulating a point source. The output is radially diverging, but is harnessed by enclosing the sphere within a mirrored ellipse to image the output to a point, or within a mirrored parabola to columinate the emission. A concentric, reflective inner sphere may be disposed in the cavity, with the amplifying medium lying between the two spheres. A voltage potential is applied between the spheres to excite the medium.

摘要： The present disclosure relates to a ring-type laser system supporting circumferential radial emission. A cylindrical ring waveguide provides optical confinement in the radial and axial dimensions supporting a plurality of traveling wave modes with various degrees of confinement. The waveguide contains a gain media which is gain tailored to offset modal confinement factors of the modal constituency to favor radial emission. The selected modes radiate energy as they circulate the laser resonator with a 360 degree output coupler. The design is applicable toward both micro-resonators and resonators much larger than the optical wavelength, enabling high output powers and scalability. The circumferential radial laser emission can be concentrated by positioning the cylindrical ring laser inside a three-dimensional conical mirror thereby forming a laser ring of light propagating in the axial dimension away from the surface of the laser, which can be subsequently collimated for focused using conventional optics.

摘要： The present disclosure relates to a three-dimensional cylindrical cavity-type laser system capable of supporting circumferential radial emission. A cylindrical ring waveguide provides optical confinement in the radial and axial dimensions thereby supporting a plurality of radial modes, one of a plurality of axial modes and a plurality of degenerate azimuthal modes. These modes constitute a set of traveling wave modes which propagate around the cylindrical ring waveguide possessing various degrees of optical confinement as quantified by their respective Q-factors. Index tailoring is used to tailor the radial refractive index profile and geometry of the waveguide to support radial modes possessing Q-factors capable of producing efficient radial emission, while gain tailoring is used to define a gain confining region which offsets modal gain factors of the modal constituency to favor a preferred set of modes supporting efficient radial emission out of the total modal constituency supported by the resonator.. Under appropriate pump actuation the selected modes produce circumferential laser radiation with the output surface comprising of the entire outer perimeter of the cylindrical ring waveguide. The design is applicable toward both micro-resonators and resonators much larger than the optical wavelength, enabling high output powers and scalability. The circumferential radial laser emission can be concentrated by positioning the cylindrical ring laser inside a three-dimensional conical mirror thereby forming a laser ring of light propagating in the axial dimension away from the surface of the laser, which can be subsequently collimated for focused using conventional optics.

摘要： The present disclosure relates to index guided semiconductor laser devices supporting wide single lateral mode operation for high power operation. A narrow channel ridge waveguide structure is presented which devices can be configured as single lateral multi-spectral high power semiconductor lasers, single frequency lasers, gain chips and semiconductor amplifiers. More specifically it relates to a means for increasing the lateral mode size over that of conventional index guided structures to increase the average output power typically limed by Catastrophic Optical Damage (COD) at the laser facet or by intensity related effects. This potentially allows the overall laser cavity length to be shortened for a given output power level to stabilize frequency locking with internal or external gratings to improve single frequency operation.

摘要： A spherical laser includes a transparent or semi-transparent outer spherical vessel having an internal cavity, an amplifying medium in the cavity, and means to excite the amplifying medium. The sphere is provided with a partially reflective coating to act as a spherical optical resonator. The spherical resonator includes a plurality of optically different regions containing alternative optical media from the cavity medium differing in bulk optical parameters utilized for mode tailoring. The optically different regions work collectively to exclude the whispering gallery modes from those supported by the spherical cavity. Excitation of the amplifying medium produces an optical gain. When the gain exceeds cavity losses and threshold conditions are met, lasing is supported. This creates a three-dimensional, spherically radiating emission, emulating a point source. The sphere is enclosed within a mirrored ellipse to image the output to a point, or within a mirrored parabola to columinate the emission.

摘要： A quasi-static bend sensor is taught that comprises a layering of a plurality of ionic polymer metal composite (IPMC) sections with intervening dielectric sections in a vertical stack configuration. The IPMC sections are electrically connected in parallel. The surface of the stack is coated with high-purity synthetic isoparaffins for polymer hydration to increase step response consistency. Finally, the vertical stack configuration is electrically connected to an electric field measurement device and a linear quadratic regulator based controller for reducing settling time.
