摘要： A biasing circuit for a photodiode. The novel biasing circuit includes a first system for setting a reference gain threshold, a second system for setting an operating gain threshold, and a third system for adjusting a bias of the photodiode until a ratio of the operating gain threshold to the reference gain threshold is equal to a predetermined factor Z. In an illustrative embodiment, the reference gain threshold corresponds to a given probability of an output of the photodiode crossing the reference gain threshold when the photodiode is operating at a reference gain bias, and the operating gain threshold corresponds to a given probability of the photodiode output crossing the operating gain threshold when the photodiode is operating at an operating gain bias. The predetermined factor Z is a ratio of noise at a desired operating gain of the photodiode to noise at the reference gain of the photodiode.

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

摘要： According to the present invention, light is provided to an elliptical optical surface (102) separating first and second homogeneous optical media (104), (106) that cause collimated light (108) originating in one of the media to be perfectly focussed either at a primary focus within the second medium or at a virtual focus within the first medium (110). For example, a collimated beam (510) is expanded by refraction in an immersion refractive confocal ellipsoid optic (502) having an input optical surface (504) and output optical surface (506). Further, the elliptical optical surface is used in combination with a second optical surface such that both surfaces share a common optic axis and are separated by an optically transmissive medium such as glass and spaced such that the optical focal points of both surfaces are common to create an immersion optical beam expander. Still further, said optical surface (1112) includes a lens element in a one or two dimensional lens array responsive to light from a light emitting diode or laser diode bar in a diode array.

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 with 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 light 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 flexiblity and motion of the stabilized platform. Four different embodiments are described in which the phase conjugation mirror is based on stimulated Brillouin scattering, degenerate four-wave mixing, three-wave mixing, and photon echo effects, respectively.

摘要： Method of manufacturing a laser medium with a material having a surface and a dopant in the material distributed whereby the material has a spatially variant optical flux density profile uses tailored non-uniform gain profiles within a Yb:YAG laser component (rod, slab, disc, etc.) 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. By reducing proportionally more Yb3+ ions at the unmasked areas of component, than in the masked areas, the coordinate-dependent or spatially-controlled gain profiles are achieved. The material can be used for the fabrication of laser rods, slabs, etc. with various concentrations and spatial localizations of dopants.

摘要： A beam control system and method. The system includes an illuminator for providing a first beam of electromagnetic energy at a first wavelength; a source for providing a second beam of electromagnetic energy at a second wavelength; and an arrangement for compensating wavefront errors in the second beam using a bias representative of a comparison between the first wavelength and the second wavelength. In the illustrative embodiment, the arrangement includes a processor which corrects wavefront errors using a bias representative of a difference between said first wavelength and said second wavelength. In the disclosed application, a target wavefront sensor is included and the laser is a high-energy laser beam. The wavefront errors include a chromatic aberration and the errors are compensated using a deformable mirror and a correction algorithm executed by an adaptive optics processor. In one alternative embodiment, the errors are compensated using an optical aberration corrector. The aberration corrector may be a holographic optical element or other suitable device. In another alternative embodiment, the errors are corrected with the above embodiment in combination with the use of “woofer” and “tweeter” correcting elements with the woofer being a long stroke low frequency element and the tweeter being a short stroke high frequency element.
