摘要： An immersion cooled semiconductor laser assembly includes an electrically activated semiconductor laser device, such as a two-dimensional laser diode array, and liquid coolant flowing thereabout which directly contacts the emitting facet of the semiconductor laser device. The semiconductor laser assembly also includes first and second electrodes for supplying electrical energy to the semiconductor laser device such that the semiconductor laser device emits a laser output through its emitting facet. During the emission of the laser output, however, the semiconductor laser device generates heat, thereby increasing the temperature of the semiconductor laser device. In order to protect the semiconductor laser device, the circulating liquid coolant draws heat from the semiconductor laser device, thereby cooling the semiconductor laser device. The liquid coolant can be a dielectric liquid coolant which is both electrically and optically passive so a to maintain electrical isolation between the first and second electrodes without absorbing the laser output of the semiconductor laser device. By efficiently cooling the semiconductor laser device, the semiconductor laser device can consistently product output pulses having a relatively high average power and a relatively high pulse repetition rate.

摘要： A system and method for combining plural low power light beams into a coherent high power light beam by means of a diffractive optical element operating as both a beam combiner and beam sampler. An oscillation source transmits a master signal that is split into plural beams propagating at a common wavelength. Each beam is phase locked by a corresponding phase modulator according to a phase correction signal. The beams are directed through a fiber array to the diffractive optical element to allow efficient coherent combination of the beams at a desired diffraction order. The diffractive optical element includes a periodic sampling grating for diffracting a low power sample beam representative of the combined beam. A phase detection stage detects phases of constituent beams in the sample beam from which the phase correction signals are derived and fed back to the phase modulators. The diffractive optical element may be further modified to collimate beams diverging from the fiber array and to focus the sample beam onto a phase detector.

摘要： A solid-state laser system includes a solid-state laser having a laser gain medium and at least one pumping diode. The system also includes a thermal management system capable of placing a coolant in thermal communication with the solid-state laser such that the coolant can carry heat away from the solid-state laser. The thermal management system is then capable of rejecting the heat carried away by the coolant to a fluid at an ambient temperature, where the coolant can be at a temperature between 40° C. and 80° C. when the thermal management system rejects the heat. Advantageously, the thermal management system of the present invention can include reject the heat to a fluid comprising, for example, air or water. As such, the thermal management system does not require separate cooling of the fluid carrying the heat away from the coolant.

摘要： An optical fiber amplifier employing a prism to optimally couple pump energy into the pump core of a dual clad fiber. The optical fiber amplifier consists of a dual clad fiber having an inner (e.g., signal) core, an outer (e.g., pump) core surrounding the inner core, and a cladding layer at least partially surrounding the outer core. Pump energy can be injected into the outer core through the prism located adjacent to the outer core in order to amplify signals propagating through the inner core.

摘要： A micro-doppler microscope for providing an indication of the vibration of a target. An input laser beam is received by a beamsplitter that divides the input laser beam into a transmitted portion and a reflected portion. A first focusing optics focuses the transmitted portion onto a target, the target scattering a scattered portion thereof. This scattered portion is directed back through the first focusing optics, and reflected off the beamsplitter. Second focusing optics is positioned to receive the scattered portion from the beamsplitter and for focusing the scattered portion. A planar mirror is positioned to reflect the reflected portion of the input laser beam back through the beamsplitter and through the second focusing optics so that it is focused. A fast photodetector receives the focused scattered portion from the second focusing optics and the focused reflected portion from the second focusing optics. Both focused portions are focused on the same spot on the fast photodetector. Coherent mixing of the focused portions occurs at the fast photodetector, the frequency modulation of the scattered portion thereby providing an indication of the vibration of the target. The indication is provided as an output signal from the fast photodetector.

摘要： An electron beam pumped semiconductor laser includes a semiconductor laser screen and an electron beam source adjacent the semiconductor laser screen. The semiconductor laser screen comprises a transparent single crystal substrate, an electron beam responsive active gain layer on the substrate, and first and second reflective layers. The epitaxial electron beam responsive active gain layer has a crystal structure in alignment with the crystal structure of the substrate, and the first and second reflective layers define a laser cavity through the epitaxial electron beam responsive active gain layer therebetween. The electron beam source generates an electron beam which impinges on the epitaxial electron beam responsive active gain layer thereby generating a laser output. Accordingly, the single crystal active gain layer can be formed on the substrate by epitaxial deposition techniques increasing the performance and reliability of the electron beam pumped semiconductor laser.

摘要： A three-dimensional (3-D) virtual display system for displaying a flicker-free 3-D virtual image to each of N viewers randomly dispersed about a horizontally disposed viewing screen, where N is an integer greater than 1, includes a laser projector for generating N.times.M image pairs responsive to a video signal comprising the N.times.M image pairs, N transmitters associated with respective ones of the N viewers, each of the N transmitters generating a unique coded pulse, a detector for determining the position of each of the N viewers relative to the viewing screen responsive to the respective unique coded pulse and for generating respective position data, a graphics processor for generating the video signal responsive to the position data, and N selectors associated with the N viewers for selecting the M image pairs out of the N.times.M image pairs allocated to each of the N viewers, respectively. The projector includes an electron-beam-pumped semiconductor laser (EBSL) screen, e.g., a vertical cavity surface emitting laser screen. In an exemplary case, the video signal carries in excess of 1000 image pairs per second, which is far beyond the capability of conventional cathode ray tubes (CRTs) to display. A method for generating N 3D virtual images and a corresponding video signal are also described.
