Abstract: A method and a system for optimizing the alignment of an optical system, such as a telescope, using a multi-degree-of freedom (DOF) actuator/hexapod and star field images. The method iteratively adjusts the hexapod in all DOFs using the damped least squares (DLS) optimization algorithm and dynamically changes the size of pixel windows to measure ensquared energy (ES) as a closed loop feedback.

Abstract: A method of improving optical characteristics of an optical window operating in a flow of fluid and having first and second panes of optically transmissive material—each having an edge adjacent to, parallel with, and at least partially coextensive with each other—is described herein. The method includes inserting a thermally conductive blade between two adjacent edges of the first and second panes of optically transmissive material; and lifting an adverse flow stagnation zone forward of the optical window by protruding the thermally conductive blade into the flow of fluid from an outer surface of the panes of the optical window.

Abstract: An apparatus includes a non-linear optical crystal configured to perform harmonic wavelength conversion. The apparatus also includes first and second heaters contacting opposite sides of the optical crystal, where the first and second heaters are configured to heat the optical crystal. The apparatus further includes first and second backing plates configured to hold the first and second heaters in contact with the optical crystal. The apparatus also includes an internal mount defining a space configured to receive at least a portion of the optical crystal. In addition, the apparatus includes an external cover around at least a portion of the internal mount.
