摘要： An optical window may be configured to minimize optical aberrations. The optical window may include a laminous optical window assembly. The laminous optical window assembly may have four or more alternating layers of positive refraction material layers and negative refraction material layers. The four or more alternating layers may be configured to minimize refraction of electromagnetic rays propagating therethrough such that a given incident electromagnetic ray is substantially collinear with a corresponding transmitted electromagnetic ray.

摘要： A material having a surface and a dopant in the material distributed whereby the material has a spatially variant optical flux density profile. In accordance with the invention, tailored non-uniform gain profiles within a Yb:YAG laser component (rod, slab, disc, etc.) are achieved by a spatial material modification in the spatially masked pre-forms. High temperature-assisted reduction leads to the coordinate-dependent gain profiles, which are controlled by the topology of the deposited solid masks. The gain profiles are obtained by reducing the charge state of the laser-active trivalent Yb3+ ions into inactive divalent Yb2+ ions. This valence conversion process is driven by mass transport of ions and oxygen vacancies. These processes, in turn, affect the dopant distribution throughout the surface and bulk laser crystal.

摘要： A solid state, laser light control device (20, 30) and material (10), and methods of producing same. The device (20, 30) and material (10) consist essentially of a host material (14) which contains: a dopant species (16) at a first valence state (a), the concentration of which increases with distance from the surface (18); and the same dopant species (16) at a second valence state (b), the concentration which decreases with distance from the surface (18). The method comprises the steps of: obtaining a doped solid state material (14); exposing the solid state material (14) to elevated temperature, for a period of time, in an oxidizing or reducing atmosphere. The elevated temperature and time of exposure are selected to change the valence state (a) of the dopant (16) in direct proportion to distance from the surface (18) of the solid state material (16). What is thereby produced is a solid state device (20, 30) in which the concentration of the dopant 16 at the second valence state (b) decreases with radius, the concentration of the dopant (16) at the first valence state (a) increases with radius, and the sum of these concentrations remains constant.

摘要： A concentrator including a volume of at least partially transmissive material and a plurality of facets disposed at at least one surface thereof. Each of the facets is disposed at a position dependent angle relative to the surface effective to cause an internal reflection of energy applied to the layer whereby the density of the applied energy varies as a function of position. In the illustrative implementation, the volume is an active medium, i.e., a slab. The slab has substantially parallel, planar upper and lower surfaces and first and second edges therebetween. A plurality of cladding layers are disposed on the upper and lower surfaces of the slab. The facets are provided in the cladding layers on the upper and lower surfaces of the slab and angled as a function of distance relative to the first or the second edge. The facets provide a Fresnel reflecting surface or a binary optic surface.

摘要： A method and apparatus are disclosed for providing a laser beam that is automatically aligned with a substantially rigid, stabilized platform or frame that can be oriented over a wide angular range, such as by the gimbals of a laser pointing and tracking system. A single-transverse-mode master laser oscillator 12 is mounted on the stabilized platform 13 which is part of the inner gimbal, which can be rotated about an elevation axis 16, and a multipass laser amplifier 21 wiht a phase conjugation mirror 22 and an optional nonlinear frequency-conversion device 20 are located off the inner gimbal. An outer gimbal or pedestal mount permits rotation about an azimuthal axis 17. The laser oscillator 12 and laser amplifier 21 are coupled by means of a beamsplitter 15 and two reflecting elements 18 and 19. The laser media used for the oscillator 12 and amplifier 21 are either the same, or compatible media having the same wavelength. In an alternative embodiment the two reflecting elements are replaced by a flexible ligh waveguide such as a glass fiber. The phase conjugation mirror 22 compensates the beam for the effects of optical aberrations caused by thermally induced changes in the amplifier medium and the nonlinear medium (if used) and also compensates the beam for angular tilt and jitter in the beam line of sight due to structural flexibility and motion of the stabilized platform. Four different embodiments are described in which the phase conjunction mirror is based on stimulated Brillouin scattering, degenerate four-wave mixing, three-wave mixing, and photon echo effects, respectively.

摘要： A method and apparatus are disclosed for providing a self-aligning phase conjugate laser beam that is automatically boresighted with an active or passive tracking sensor. A single-transverse-mode laser oscillator 12 and a tracking sensor 14 are mounted on opposite sides of an output coupling beamsplitter 15, all attached to a stabilized platform 13 which is part of the inner gimbal of a pointing and tracking system. A multipass laser amplifier 21 with a phase conjugation mirror 22 and an optional nonlinear frequency-conversion device 20 are located off the inner gimbal. The inner gimbal allows rotation of the stabilized platform about an elevation axis 16, and an outer gimbal or pedestal mount permits rotation about an azimuthal axis 17. The phase conjugation mirror 22 compensates the beam for the effects of optical aberrations caused by thermally induced changes in the amplifier medium and the nonlinear medium (if used) and also compensates the beam for angular tilt and jitter in the beam line of sight due to structural flexibility and motion of the stabilized platform. Part of the oscillator output passes through the beamsplitter to the tracking sensor to mark the far-field location of the amplified output beam. The tracking sensor also views a target image after it is reflected by the beamsplitter. The tracking system measures the angular displacement between the target aimpoint and the locus of the output beam as marked by the oscillator and generates tracking error signals which are used to close a servomechanical feedback loop around the gimbal orientation apparatus. Pointing errors resulting from misalignment of the oscillator, the tracking sensor, and the beamsplitter are compensated by this technique.
