摘要： A laser crystal (25) having a relatively short optical length functions as a seed laser (1) and simultaneously establishes the wide separation between longitudinal modes. Pulsed operation causes multiple longitudinal modes to co-exist before competition acts to extinguish modes. The seed laser (1) is isolated from the relatively higher peak power output beam (4). Further, the injection seeded slave resonator (6) optical cavity length is adjusted by mechanical, electromechanical and/or electro-optical component(s) to harmonize the slave resonator optical cavity to the seed laser (1) optical cavity. A number of widely separated longitudinal modes are simultaneously output as a pulsed, high optical quality beam having a broad frequency range, short temporal coherence, and stable simultaneous operation of the several modes.

摘要： 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 and an aberrator to increase the angular spread. In the specific embodiment, an opaque plate, with a pinhole aperture 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.

摘要： In various embodiments, a semi-guiding optical fiber includes a core having a first refractive index and a high aspect ratio elongated cross-section along a slow axis direction. First and second signal claddings having a second refractive index sandwich the core. A third cladding having a third refractive index substantially surrounds at least side edges of the core.

摘要： The inventive rod includes a gain medium having first and second equal length portions sharing a common optical axis and an optical rotator disposed between said first and second portions which optical rotator compensates for birefringence. In an exemplary case, the optical rotator includes first and second waveplates optically coupled to one another and oriented with respect to one another by a predetermined angle, where the first waveplate receives a polarized beam having a first state, and the second waveplate produces the polarized beam having a second state, the first and second states differing from one another by 90°. Multiple rotators can be employed to compensate strongly birefringent rods, each rotator compensating a section of a rod constructed from a plurality of equal length optical gain elements.

摘要： A waveguide coupler for coupling electromagnetic power between a first rectangular waveguide and a second rectangular waveguide includes a one-dimensional intermediate waveguide formed of two plates spaced apart by a distance equal to a common height of the two waveguides. This enables a wave emanating from the first waveguide to spread apart transversely so as to equal the width of the second waveguide, the width of the second waveguide being greater than the width of the first waveguide. A cylindrical lens is located between the intermediate waveguide and the second waveguide to provide for a conversion between a cylindrical wavefront and a planar wavefront. The coupler is operative in reciprocal fashion such that a wave emanating from the first waveguide spreads out in width and is then converted to a planar waveguide prior to entering the second waveguide; and a wave emanating from the second waveguide is converted to a wave of contracting width for entry into the first waveguide. In each of the first and the second waveguides, the waveguide has an open end which serves as a port by which electromagnetic power is coupled between the waveguide and the intermediate waveguide. In an alternative embodiment, the intermediate waveguide may be fabricated as a block of solid electromagnetic-wave propagating material.

摘要： This invention discloses a narrow field of view scanner (10) incorporating two multi-faceted polygon scanning wheels (12, 16) having a slightly different number of facets (14, 18). Each scanning wheel (12, 16) turns at an angular rate such that a facet (14) on one wheel (12) rotates through a predetermined field of view at the same rate as a facet (18) on the other wheel (16). Further, each of the scanning wheels (12, 16) scan in opposite scanning directions. This does not necessarily mean, however, that the wheels are actually rotating in opposite directions. Because both of the scanning wheels (12, 16) are scanning in opposite directions, the scanning of one scanning wheel (16) substantially cancels the scanning of the other scanning wheel (12). Because of the difference in the number of facets (14, 18) between the two scanning wheels (12, 16), the scanning is not entirely cancel out. By this configuration, a dual multi-faceted scanning wheel can scan a much narrower field of view which could be scanned by a single scanning wheel having the same number of facets. The scanning wheels (42, 44) can be configured relative to each other in a variety of different manners, including rotating about a common axis, to satisfy specific design and space requirements of a scanning system.

摘要： A method and apparatus which corrects the amplutide variation in the output in an electro-optic modulated laser system (10). Birefringence within the electro-optic crystal (25) causes elliptical polarization of the linearly polarized laser light (22) produced by the laser gain medium (16), in turn causing a loss in the laser output (27). The loss owing to the elliptical polarization is corrected by either applying a D.C. bias from voltage source (30) directly to the electro-optic crystal (25) or by inserting a quarter-wave plate (32) within the laser's resonant cavity.
