摘要： A planar laser gain medium and laser system. The novel laser gain medium includes an active core having a high aspect ratio cross-section with a fast-axis dimension and a slow-axis dimension, signal claddings adapted to form reflective boundaries at fast-axis boundaries of the core, and a material adapted to minimize reflections at slow-axis boundaries of the core. In an illustrative embodiment, the laser gain medium is an optical fiber. The core and claddings form a waveguide adapted to control modes propagating in the fast-axis direction. When the laser gain medium is employed as a laser oscillator, a high reflectivity mirror and an outcoupler are positioned at opposite ends of the core to form a laser resonator adapted to control modes in the slow-axis direction.

摘要： A system for removing waste energy in the form of sensible heat and fluorescent energy from a solid state laser medium having a broad surface. The system includes a manifold disposed about the laser medium having a plurality of inlet jets interspersed with a plurality of exhaust orifices. Coolant fluid is circulated through the manifold. The fluid is forced through the plurality of inlet jets to impinge the broad face of the laser medium, thereby transferring waste energy by convection from the laser medium to the coolant fluid. The coolant fluid is further circulated to exhaust the pumphead manifold through the plurality of exhaust orifices. The fluorescent energy, which is radiated from the laser medium, is converted to sensible heat by an absorber disposed within the coolant adjacent to the laser medium. The coolant then removes the converted heat by forced convection. The absorber can be suspended particles in the coolant fluid or a porous material supported in the manifold at some distance from the laser medium.

摘要： A loop four-wave mixing phase conjugator that can be used with depolarized signal beams comprises a polarization separator, a polarization mixer, an optical diode, a gain medium and relay optics that together form a unidirectional laser resonator. In operation, the polarization separator separates a signal beam .epsilon..sub.1 into orthogonally polarized signal beam components .epsilon..sub.11 and .epsilon..sub.12 and directs them to a nonlinear medium. The components propagate through the nonlinear medium and emerge as loop beam .epsilon..sub.2, with orthogonally polarized components .epsilon..sub.2 and .epsilon..sub.22. The polarization mixer mixes the energy from the two orthogonally polarized loop beam components, and relay optics direct the loop beam components back to the nonlinear medium at an angle with respect to the input beam. The loop beam components intersect and optically interfere with signal beam components .epsilon..sub.11 and .epsilon..sub.22 in the nonlinear medium to form gratings. The optical diode and gain medium are positioned in the optical loop so that an oscillation beam .epsilon..sub.3 builds up from optical noise in the resonator and oscillates in a direction counter to the propagation direction of loop beam components .epsilon..sub.21 and .epsilon..sub.22. A portion of oscillation beam .epsilon..sub.3 is transmitted by the gratings, and exits the optical loop as an output beam .epsilon..sub.4. .epsilon..sub.3 is phase conjugate to the input beam .epsilon..sub.1 in both the spatial and polarization senses.

摘要： A compact loop four-wave mixing phase conjugator that can be used in practical optical applications comprises a reflective nonlinear cell, relay optics, an optical gain medium, and an optical diode that together form a unidirectional ring laser resonator. In operation, a signal beam .epsilon..sub.1 is directed to the nonlinear cell, where it passes through a nonlinear medium contained within the cell and is reflected out of the cell as loop beam .epsilon..sub.2. The relay optics direct loop beam .epsilon..sub.2 through the optical diode, optical gain medium, and back to the nonlinear cell, where it intersects and optically interferes with the signal beam .epsilon..sub.1 to form a refractive index grating in the nonlinear medium. The optical diode and gain medium are positioned in the loop so that an oscillation beam .epsilon..sub.3 builds up from optical noise in the resonator and oscillates in a direction counter to the propagation direction of loop beam .epsilon..sub.2. A portion of oscillation beam .epsilon..sub.3 is transmitted by the refractive index grating, reflects off the reflective portion of the nonlinear cell and emerges from the cell as phase conjugate output beam .epsilon..sub.4.

摘要： A laser gain medium. The novel laser gain medium includes a host material, a plurality of quantum dots dispersed throughout the host material, and a plurality of laser active ions surrounding each of the quantum dots. The laser active ions are disposed in close proximity to the quantum dots such that energy absorbed by the quantum dots is non-radiatively transferred to the ions via a Forster resonant energy transfer, thereby exciting the ions to produce laser output. In an illustrative embodiment, each quantum dot is surrounded by an external shell doped with the laser active ions.

摘要： A glaze encapsulated solid-state laser component. The novel laser component includes a core and a cladding of ceramic glaze disposed on a surface of the core. In an illustrative embodiment, the core is fabricated from a laser gain medium and the cladding material is a multi-oxide eutectic ceramic glaze having a refractivity slighter lower than the refractivity of the gain medium, such that the glaze layer forms a step-index refractivity interface cladding that can effectively suppress parasitic oscillations in the core gain medium. The glaze cladding can be applied by coating the core with the glaze and then firing the glaze coated core, or by fabricating pre-formed cladding strips from the ceramic glaze in a first firing cycle, mounting the pre-formed strips to the core, and then fusing the pre-formed strips to the core in a secondary firing cycle.
