Abstract: A system (40) for setting the bias of a device (12). The novel bias setting system (40) includes a first system (50, 70) for determining a ratio between noise at an operating gain of the device (12) and noise at a reference gain of the device (12), and a second system (90) for adjusting the bias until that ratio is equal to a predetermined factor Z. The reference gain is the unity gain or reach-through gain of the device (12). In an illustrative embodiment, the first system (50, 70) is adapted to measure the noise at operating gain by determining an operating gain threshold, and measure the noise at the reference gain by determining a reference gain threshold. The second system (90) then adjusts the bias until the ratio of the operating gain threshold to the reference gain threshold is equal to the predetermined factor Z.

Abstract: A spatial filter adapted to increase the angular spread of non-conjugated energy in a beam and suppress this energy to improve the efficiency of a phase conjugate system. In the illustrative embodiment, the filter includes first and second lenses (81, 83) and an aberrator (86) to increase the angular spread. In the specific embodiment, an opaque plate (84), with a pinhole aperture (82) therethrough, is sandwiched between the lenses to suppress the non-conjugated energy. The aberrator may be implemented with an amplifier or other suitable mechanism. Likewise, the aperture may be replaced with a highly angle-selective thick Bragg grating or other suitable arrangement. A phase conjugate master oscillator/power amplifier laser architecture is also disclosed. In an illustrative embodiment, the novel architecture includes a master oscillator adapted to output a laser beam; a power amplifier beam line in optical alignment with the beam; a mechanism for creating a beam having phase conjugate energy and non-conjugated energy; and at least one inventive spatial filter in alignment with the amplifier. The inventive filter is adapted to increase the angular spread of non-conjugated energy in a beam and suppress this energy to improve the efficiency of the system. In a specific implementation, the beamline includes plural amplifiers, each with one of the novel spatial filters disposed therebetween.

Abstract: A beam control system and method. The inventive system includes an arrangement for receiving a first beam of electromagnetic energy; measuring wavefront aberrations in the first beam with a wavefront sensor; and removing global tilt from the measured wavefront aberrations to provide higher order aberrations for beam control. In the illustrative embodiment, the invention uses a traditional (quad­cell) Shack-Hartmann wavefront sensor to measure wavefront aberrations. An adaptive optics processor electronically removes the global tilt (angular jitter) from this measurement leaving only the higher-order Zemike components. These higher­order aberrations are then applied to wavefront control elements, such as deformable mirrors or spatial light modulators that correct the tracker image and apply a conjugate distortion to the wavefront of the outgoing HEL beam. A track error (angular jitter) component is supplied by a separate fine track sensor. This jitter error is then applied by the adaptive optics processor to a fast steering mirror, which corrects jitter in the tracker image and applies a compensating distortion to the LOS of the HEL beam.

Abstract: An optical system (20) has a light source (52) of an optical beam (54), and a wavefront distortion generator (56) that introduces a known wavefront distortion into at least one wavelength component of the optical beam (54) prior to the formation of an intermediate image. A focusing device (58) receives the optical beam (54), produces the intermediate image of the optical beam (54), and outputs the optical beam (54). A wavefront distortion corrector (60), after the formation of the intermediate image, introduces a wavefront distortion correction into each component of the optical beam (54) into which the known wavefront distortion was introduced by the wavefront distortion generator (56). The wavefront distortion correction is the reverse of the known wavefront distortion introduced into the optical beam (54) by the wavefront distortion generator (56).

Abstract: An efficient multi-emitter boresight reference source (12). The efficient reference source (12) includes a first mechanism (182) for transmitting a first portion of electromagnetic energy (184) within a first waveband. A second mechanism (186) transmits a second portion of electromagnetic energy (188) within a second waveband different than the first waveband. A third mechanism (148) for combining the first portion of electromagnetic energy and the second portion of electromagnetic energy to yield a uniform reference beam (28). In a specific embodiment, the first mechanism (182) includes a first emitting structure (182), and the second mechanism (186) includes a second emitting structure (186). The first emitting structure (182) and the second emitting structure (186) are semiconductor laser emitting structures. The first waveband (184) and second waveband (188) correspond to wavebands of one or more sensors employing the boresight reference source (12) for beam­alignment purposes. The wavebands (184, 188) include visible and/or infrared portions of the electromagnetic spectrum. The first waveband (184) and second waveband (188) are sufficiently different to eliminate undesirable coupling between first and second laser cavities (182, 186) associated with the first and second emitting structures (182, 186), respectively. The uniform reference beam (28) is a collimated, co-aligned, and multi-spectral reference beam (28), and at least one of the first and second emitting structures (182, 186) includes a Quantum Cascade Laser (QCL) emitting structure. The first emitting structure (182) includes multiple QCL repeat units within a common waveguide region of the first emitting structure (182). The multiple QCL repeat units have different superlattice compositions and/or quantum well thickness, sufficient to cause the first emitting structure (182) to operate at different wavelengths to enhance uniformity of the uniform reference beam (28). The multiple QCL repeat units may also be identical repeat units operating at different temperatures to generate different center wavelengths within each waveband (184, 188). Alternatively, the first emittting structure (182) includes multiple identical QCL

Abstract: Air core optical fiber structures in which the cladding is composed of an engineered optical metamaterial having a refractive index less than unity for at least one specific wavelength band and provides for total internal reflection of optical energy between the air core and metamaterial cladding. According to certain examples, a method of guiding optical energy includes constructing a hollow core optical fiber with an all-dielectric optical metamaterial cladding, coupling optical energy into the optical fiber having an operating wavelength near a resonance of the metamaterial cladding, and guiding the optical energy within the hollow core optical fiber by total internal reflection. A method of manufacturing the optical fiber is disclosed, based on constructing a first fiber preform comprising glass rods of a first refractive index arranged in a lattice pattern interspersed with a glass substrate having a second refractive index, drawing this first preform to produce a first optical fiber and then dividing the first optical fiber into segments which are arranged to construct a second preform, which is then drawn to produce the hollow core fiber with metamaterial cladding.
