摘要： A frequency-doubled, edge-emitting semiconductor laser includes a separate confinement heterostructure surmounted by a waveguide including a converting layer of a periodically poled, optically nonlinear material. Fundamental radiation generated in the heterostructure is directionally coupled from the heterostructure into the waveguide, is converted to second-harmonic radiation in the converting layer and is delivered from the waveguide as output radiation. In one example, a distributed Bragg grating is included at an interface between the heterostructure and the waveguide for facilitating coupling of fundamental radiation from the heterostructure into the waveguide.

摘要： Laser apparatus is disclosed in which fundamental-wavelength optical pulses delivered from a mode-locked laser resonator at a pulse-repetition frequency (PRF) are converted to harmonic-wavelength pulses in an optical delay loop. One example is disclosed in which the harmonic-wavelength pulses are delivered directly from the delay loop. Another example is disclosed in which the harmonic-wavelength pulses are divided by the delay loop into a number of temporally spaced-apart replicas thereof, and the delay loop delivers bursts of replicas of different one of the harmonic wavelength pulses at a burst-repetition frequency equal to or a multiple of the PRF of the resonator.

摘要： A directly cooled diode-laser bar package includes a diode-laser bar bonded to a heat-sink. The operating temperature of the diode-laser bar can be selectively varied by varying the thermal impedance of the heat-sink in or near a region of the heat-sink on which the diode-laser bar is bonded. The thermal impedance is selectively varied by varying the insertion depth of screws inserted into corresponding screw holes extending into the heat-sink close to or immediately adjacent the region on which the diode-laser bar is bonded.

摘要： An electro-optical switch includes an optical assembly arranged to transmit laser-radiation. The optical assembly comprises an active optical crystal. On one of two opposite surfaces of the crystal is an optical window formed from a material having a refractive index lower than the material of the crystal. Heat deposited, as a result of transmission of the laser-radiation, at the surface of the crystal in contact with the widow is transferred to the window, thereby reducing the potential for optical damage to the crystal surface. The window is sufficiently thick that it has an odd integer multiple of quarter-wavelengths optical thickness at a wavelength about equal to a wavelength of the laser-radiation, thereby behaving as an antireflection device for the crystal at that wavelength. In one embodiment of the optical assembly, the active optical crystal is a cadmium telluride crystal and the window is formed from cesium bromide.

摘要： Apparatus for reducing spacing between a plurality of parallel, spaced apart plane-polarized laser-radiation beams delivered by a stack of laser-diode bars includes a ninety degree polarization rotator, and a compound prism including a total reflecting surface an internal polarization-selective surface parallel to each other. The polarization-selective surface is highly transmissive for radiation plane-polarized in one polarization orientation and highly reflective for radiation plane-polarized at ninety degrees to that orientation. The polarization rotator rotates the polarization of a portion of the beams. The beams are transmitted through the compound prism with the portion of polarization-rotated beams following a different path through the prism from that of the beams that are not polarization rotated. The beams exit the prism with spacing therebetween one-half of the spacing between beams entering the prism.

摘要： Fluence monitoring apparatus is disclosed for a system for modifying curvature of a cornea by selective laser photoablation of corneal tissue by means of a succession of pulses of laser radiation delivered to the cornea in an overlapping pattern corresponding to a desired pattern of photoablation. The system includes a scanning arrangement for directing the pulses to form the overlapping pattern. The fluence monitoring apparatus includes a beamsplitter located between the scanning arrangement and the cornea for directing a fraction of each of the pulses to a monitor plate. The monitor plate emits fluorescent light on being irradiated by each pulse-fraction. A video camera provides an electronic image of the monitor plate. Processing circuitry periodically records the electronic image, and the periodic image recordings are integrated to form a composite image representative of spatial distribution of laser fluence on the cornea.

摘要： A faceplate for a touch-sensitive display includes, on an outermost surface, a pattern of electrode-regions separated by spaces. A base-coating is deposited on the surface and extends continuously over the surface. The electrode-regions are formed from a layer of a conductive transparent metal-oxide deposited on the base-coating. The electrode-regions and spaces are overcoated by a protective-layer of an insulating material. For light incident on the faceplate at about normal incidence photopic reflectivity in the protective-layer-overcoated electrode-regions is within plus or minus ten percent of photopic reflectivity in the protective-layer-overcoated spaces.

摘要： A diode-laser bar stack includes a plurality of diode-laser bars having different temperature dependent peak-emission wavelengths. The stack is arranged such that the bars can be separately powered. This allows one or more of the bars to be “on” while others are “off”. A switching arrangement is described for selectively turning bars on or off, responsive to a signal representative of the temperature of the diode-laser bar stack, for providing a desired total emission spectrum.
