Abstract: A method for evaluating the motion of a moveable object relative to a reference object includes locating the reference object within a three-dimensional coordinate system having first, second, and third positional coordinates such that the position of the reference object is characterized by respective values of the first, second, and third positional coordinates. A display is providing having at least two visual indicators, each indicator being configured as an array of selectively switchable display elements. At a critical position of the moveable object, indicating an offset between the moveable object and the reference object along one of the first, second, and third positional coordinates by selectively switching at least one of the display elements of a first one of the indicators.

Abstract: A method for evaluating the motion of a moveable object relative to a reference object includes locating the reference object within a three-dimensional coordinate system having first, second, and third positional coordinates such that the position of the reference object is characterized by respective values of first, second, and third positional coordinates. A mechanism is provided having a plurality of visual indicators. A sensor is configured to detect the position of the moveable object within the three-dimensional coordinate system substantially apart from any dynamic property inherent in the movement of the moveable object.

Abstract: An integrated, low profile, high power laser light emission device is disclosed. The integrated laser light emission device provides uniform heat dissipation, as well as uniform pumping of the laser gain medium without the need for a pumping cavity. The laser system includes a pump diode array that can be mounted directly to a laser gain medium without intervening correcting optics hardware. Heat generated by the laser light emission device is cooled by a single cooling system. In the laser device, a pump diode array is preferably a Vertical-Cavity Surface-Emitting Laser (VCSEL) array. VCSEL arrays are mounted on the laser gain crystal by a metal cavity frame or metal stilts. The slightly elevated mounting of the VCSEL's enables increased cooling and maximizing the quantity of VCSEL's on the laser gain medium in order to achieve highly efficient and high power laser light output.

Abstract: An optical device has a first medium that produces more photons that exit the first medium than enter the first medium, such as a gain material. A second medium that produces light of a different wavelength than the wavelength of light incident thereon, such as a second harmonic generator. The optical device defines a cavity including the first medium and the second medium. An energy source provides energy to at least one of the first medium and the second medium so that light exits the cavity, the energy source is modified in a number of different manners such that the optical device has decreased noise output.

Abstract: A system modifies the optical properties of an object by using a light beam from a light source that is focused at a first focal point within the object to optically change a first location within the object at the first focal point. The light beam is focused at a second focal point within the object to optically change a second location within the object at the second focal point. The light beam is focused at a third focal point within the object to optically change a third location within the object at the third focal point The object is moved relative to the light beam while creating the optical change at the second location.
