Abstract: A method for thermally stabilizing an optical parametric oscillator (OPO) 10 to maintain constant optical path length for stable high power output places a beam dump 32 outside an OPO cavity 18. The OPO 10 has a nonlinear crystal 22 within cavity 18 for splitting a single input pump beam 14 into lower energy signal and idler beams 16, 18. The method includes providing a cavity exit port for unconverted pump and generated idler beams, and absorbing unconverted beams in beam dump 32. The method includes athermalization by actively cooling surfaces used as an optics mounting base, and athermalization by constraining the size of cavity 18 by using thermally stiff members, guiding pins or rails, or by using bimetallic materials with different expansion.

Abstract: A method for registering machine tool and profilometer coordinates, wherein the machine tool defines a C-axis having a zero position, C=0, comprises loading a sacrificial workpiece into the machine tool; cutting several first features in a surface of the sacrificial workpiece and producing a linear machine tool motion across the workpiece; determining the centroid of each first cut feature; fitting a line to the centroids of the first cut features; and measuring angle ?0 of the line relative to the C-axis zero position. The angle ?0 is the departure in profilometer coordinates from the C=0 line. The method includes moving the machine tool to a fixed radius; cutting several second features in a surface of the sacrificial workpiece and producing a circular machine tool motion across the workpiece; determining the centroid of each second cut feature; fitting a circle to the centroids of the second cut features; and determining a center of the circle.

Abstract: A laser array and method of making same has precision fiducial marks that aid in the alignment of the laser array. The invention requires forming additional optical features adjacent to the laser array that is used to write fiducial marks on an opposite surface in the medium containing the laser array. Fiducial marks are formed when high intensity collimated beams of light are directed through the optical features onto a treated portion of the transparent medium. Fiducial accuracies of 1 micron are possible by using this approach.
