  • Apparatus and method for producing an annular composite far-field patterned beam(s)
    Patent number: 9042017
    Abstract: Method and apparatus to generate a composite far field beam having a central null and discrete cylindrical symmetry. A phased array of Gaussian beams was used to form an annular far-field pattern as opposed to the normal peaked pattern in most phased arrays. This annular pattern arises from the radial symmetry of the polarization in each beam. Beams opposite one another in the annulus are polarized in the same direction but are 180° out of phase. This causes the center portion of the beam to be a null rather than a peak.
    Type: Grant
    Filed: March 24, 2014
    Date of Patent: May 26, 2015
    Assignee: The United States of America as Represented by the Secretary of the Navy

  • 2.7 .mu.M laser crystalline material utilizing multiple-channel optical pumping
    Patent number: 5982796
    Abstract: A Cr/Tm/Er-doped, yttrium- or lutetium-garnet host material crystal for a solid-state laser, wherein about 3 to about 8 atomic percent of the yttrium or lutetium, respectively, crystallographic sites are occupied by Tm.sup.3+ ions, about 7 to about 22 atomic percent of the yttrium or lutetium, respectively, crystallographic sites are occupied by Er.sup.3+ ions, and about 0.6 to about 1.6 atomic percent of the octahedral sites of the garnet structure are occupied by Cr.sup.3+ ions, which crystal lases under the influence of a pumping means at a wavelength of no more than about 2.7.mu..
