  • Littman configured frequency stepped laser
    Patent number: 8218586
    Abstract: A wavelength tunable system including a laser having a lasing cavity and an external cavity, the cavities having a common optical axis; a reflective grating fixed in the external cavity; a collimating lens between the lasing cavity and the reflective grating; and an adjustable reflective mirror defining one end of the external cavity and optically coupled to the fixed reflective grating, the adjustable reflective mirror pivots about the fixed reflective grating, and a method of use as defined herein.
    Type: Grant
    Filed: November 13, 2009
    Date of Patent: July 10, 2012
    Assignee: Corning Incorporated
    Inventors: Thomas James Dunn, Jack Weston Frankovich, Christopher Alan Lee
  • X-Y adjustable optical mount with Z rotation
    Patent number: 8085482
    Abstract: An optical element mount has an inner member suspended within an outer member by a number of flexures. A first translational actuator is movable within the outer member and coupled to the inner member by a first shaft and is actuable to translate the inner member along a first substantially linear travel path within a translation plane that is orthogonal to an optical axis. A second translational actuator is movable within the outer member and coupled to the inner member by a second shaft and is actuable to translate the inner member along a second substantially linear travel path within the translation plane. A rotational actuator is movable within the outer member and coupled to the inner member by a third shaft and actuable to rotate the inner member about an instant point of rotation that is defined at the intersection of the first and second linear travel paths.
