A leveling apparatus many be used for building new construction or for releveling an existing structure. A user may place a leveling apparatus between a pier and a beam of a pier and beam foundation. The leveling apparatus may include a bottom plate that rests on the pier and a top plate that supports the beam. The bottom plate and the top plate may be separated by threaded rods. The leveling apparatus may be sufficiently small that it may fit between the pier and beam in situations where space may be limited. The user may rotate one or more nut fasteners to adjust the height between the bottom plate and the top plate. Adjusting the separation between the plates can result in leveling of a floor by adjusting the spacing between a beam and the ground.

A fluorescence concentrator system that provides for high brightness light source. The system can include a host doped with fluorescent material, which is optically pumped by an adjacent illumination source. The fluorescence concentrator captures a portion of the isotropically emitted fluorescent light and guides it to an output surface. The fluorescent energy emerging the output surface provides a high brightness light source suitable for a number of applications. For example, the fluorescence concentrator system can be used as the light source in a medical apparatus suitable for various aesthetic procedures. Further aspects of the fluorescent concentrator system can include providing for controlling the illumination source to output pumping energy suitable for high energy applications.

Control of average wavelength-converted power and/or wavelength converted pulse energy is described. One or more seed pulses may be generated and amplified with an optical amplifier to produce one or more amplified pulses. The amplified pulses may be wavelength converted to produce one or more wavelength converted pulses characterized by an average wavelength-converted power or pulse energy. Wavelength-converted power or pulse energy may be controlled by adjusting wavelength conversion efficiency without substantially changing the amplified power or pulse energy. Average wavelength-converted power may be controlled over a time scale comparable to a pulse period of the amplified pulses without adjusting an average power of the amplified pulses over the time scale comparable to a pulse period of the amplified pulses. A wavelength-converted optical system, may comprise a seed source, an optical amplifier optically coupled to the seed source, a wavelength converter optically coupled to the optical amplifier; and a controller operably coupled to the seed source and/or optical amplifier and/or wavelength converter. The controller may include logic adapted to control an average wavelength-converted power of an output of the wavelength converter over a time scale comparable to a pulse period of amplified pulses from the optical amplifier without adjusting an average power of the amplified pulses over that time scale. Alternatively, the controller logic may be adapted to control wavelength-converted pulse energy by adjusting the wavelength conversion efficiency without substantially changing the pulse energy of the amplified pulses.

A laser-radiation source includes a laser delivering an output beam, a lens, and an optical arrangement for dividing the output beam into a main beam and an auxiliary beam. The main and auxiliary beams are coupled by the lens into entrance faces of respectively a main optical fiber and an auxiliary optical fiber. The entrance face of the main optical fiber is located on the optical axis of the lens. The entrance face of the auxiliary optical fiber is laterally displaced from the optical axis of the lens.

Multi-output laser-radiation source

A light-source includes a plurality of diode-laser bars. The diode-laser bars are arranged in a parallel array and arranged to emit laser-light in the same direction. The diode-laser bars are mounted on a planar surface of a common heat-sink and are spaced-apart from each other in the emission-direction. Each diode-laser bar has one optical waveguide associated therewith. The optical-waveguides collect laser-light emitted from the diode-laser bars with which they are associated and deliver the collected laser-light to an output-aperture of the light-source. In one arrangement the diode-laser bars are mounted such that the emission-direction is parallel to the planar surface of the heat-sink, and the optical-waveguides are shaped to extend over diode-laser bars adjacent those with which they are associated. In another arrangement the diode-laser bars are mounted on the planar surface via wedge submounts such that the emission-direction is at an acute angle to the planar surface and the spacing of the diode-laser bars is selected such that the optical-waveguides can be straight yet still extend over adjacent diode-laser bars.

A light-source includes a plurality of diode-laser bars. The diode-laser bars are arranged in a parallel array and arranged to emit laser-light in the same direction. The diode-laser bars are spaced-apart from each other in the emission-direction. Optical-waveguides are provided for collecting laser-light emitted from each of the diode-laser bars and delivering the collected laser-light to an output aperture of the light-source.

Apparatus (20) for aiming and projecting laser radiation emitted from an output-face (56) at an output-end (52) of an optical-fiber transmitter (54), includes a target (26) surrounding the output-end of the optical-fiber transmitter and held in a fixed relationship therewith. One or more light sources (46) illuminate the target with visible light such that the target directs at least a portion of the visible light in the emission direction of the laser radiation whereby when the optical-fiber transmitter is directed toward a surface, the visible light directed by the target indicates an incidence region of the laser radiation on the surface. The apparatus optionally includes an optical system (27) arranged to project a visible image (72) of the target and an image (74) of the output-face of the optical fiber transmitter. The degree of focus of the visible target-image on the surface corresponds to the degree of focus of the laser radiation on the surface.

A sealed integrating reflective enclosure contains a laser diode, coupling optic, and input ends of transport fibers. A detector is positioned to capture stray scattered radiation emanating from the laser diode emitters and rear facets, coupling optic and transport fiber input ends. The detector is positioned such that stray radiation undergoes at least one reflection within the enclosure before being detected by the detector. The detector can be positioned inside the integrating enclosure, or outside the integrating enclosure opposite a detection hole that is sealed by a translucent diffuser or window. The reflected integrated light detected by the detector is an accurate indication of the optical output generated by the laser diode and coupled into the transport fibers.

A coupling system for enhanced light coupling between a laser diode and an optical fiber that includes a laser diode having an emitting surface for generating an asymmetric beam with a fast axis that is more divergent than an orthogonal slow axis thereof, an optical fiber having an input end and a delivery end, a first microlens mounted on the input side surface of the fiber, and a second microlens disposed between the laser diode and the first microlens. The input end of the optical fiber includes a beveled end surface disposed at an oblique angle with respect to a longitudinal axis of the optical fiber, and a light input side surface opposing the beveled end surface and aligned with the emitting surface of the laser diode to capture the beam emitted therefrom. The angle of the beveled surface is selected such that the beam entering the input side surface from the laser diode is total internally reflected by the beveled surface along the longitudinal axis of the fiber. The first microlens is mounted on the input side surface of the fiber in a manner to have optical continuity therewith for focusing light into the fiber and having a focal power along an axis perpendicular to the longitudinal axis of the fiber. The second microlens has a focal power along the fast axis of the beam.
