  • Patent number: 10945790
    Abstract: The disclosed invention relates to an improved system and method for treatment of soft tissue, e.g., for treatment of a snoring condition. The system can include a laser source; a hand piece; and a device for directing radiation emitted by the laser source to a treatment area (e.g., an oral treatment area). In some cases, the handpiece can include an optical element (e.g., a lens) mounted within a replaceable cartridge and adapted to modulate a laser beam such that it is non-ablative, prior to its delivery to a treatment region. In various embodiments, the system includes a CO2 laser capable of performing treatment in a more efficient manner than conventional techniques.

  • Publication number: 20190298448
    Abstract: Improved systems and methods for performing laser based treatment of hard and soft tissues, e.g., bone, skin, and connective tissue, are described. The system can feature a laser adapted to produce a peak output power significantly higher than the output power produced by conventional laser-based dental treatment systems. In some instances, the system features high definition imagers for real-time, on-axis visualization and spatial measurement of the surgical region, which can include rendering 3D images. In some implementations, the system is adapted to deliver a laser beam polarized to align with the collagen fibers of bone tissue, to enhance cutting performance. In some implementations, the system is adapted to image the treatment region with polarized light, which can enable improved visualization of nerves and other anatomical structures.

  • Patent number: 7440664
    Abstract: A microstructured optical waveguide is formed to include a periodic sequence of “plugs” of optically active material within the inner cladding air tunnels. The plugs are utilized as a grating structure for generating resonant and periodic structures. The waveguide (in one embodiment, an optical fiber) is tunable by changing the spacing of the plugs (e.g., heating the structure, changing the pressure within the structure, etc.), or by modifying the initial spacing of the plugs during the formation of the microstructured optical waveguide (i.e., by modifying the “dipping frequency” of the waveguide into a reservoir of optically active material). In general, any number of different types of optically active material may be used to form the plugs, where two or more different materials may be used in the same structure, and introduced in an alternating fashion.

  • Patent number: 7110646
    Abstract: A tunable optical fiber device comprises a length of fiber having a core having a certain refractive index; a cladding peripherally surrounding the core with a refractive index less than the refractive index of the core; and at least one hollow region disposed within the cladding in proximity to the core or within the core itself. Fluid (typically liquid) controllably moved within the hollow region modifies the effective index of the fiber and thereby tunes its characteristics.

  • Patent number: 6795617
    Abstract: An optical device including a microstructured fiber pumped by an external pulsed-light source. In one embodiment, the microstructured fiber includes two waist regions functioning as a tunable attenuator and a wavelength shifter, respectively. Output wavelength of the optical device is selected by attenuating the pump light in the first waist region and then passing the light through the second waist region to shift the pump energy to a new spectral band. An optical device of the invention configured with two or more microstructured fibers generates two or more synchronized pulsed beams, each at a different characteristic wavelength. Certain embodiments of the invention provide an inexpensive, compact, energy-efficient multi-wavelength synchronized pulsed-light source.

  • Patent number: 6782148
    Abstract: Embodiments of the invention include an optical fiber device such as a tunable birefringent optical fiber having a core region, a cladding layer therearound, and a controllable active material disposed in, e.g., selective capillaries or pockets formed in the cladding layer. The active materials include, e.g., electro-optic material, magneto-optic material, photorefractive material, thermo-optic material and/or materials such as laser dyes that provide tunable gain or loss. The application of, e.g., temperature, light or an electric or magnetic field varies optical properties of the active material, which, in turn, varies or affects the propagation properties of optical signals in the device. The optical device can include a tapered region or long period grating that causes the core mode to spread or couple into the cladding region and, simultaneously, allows the active material to be relatively close to the propagated modes, thus allowing interaction between the active material and the propagating modes.
