Livermore's Novette laser has served as a test bed facility for large aperture (74 cm) frequency conversion crystal arrays1. Crystal arrays are matrix assemblies of KDP segments sandwiched between support windows to form a monolithic structure that operates on the laser as a single optical element.

The metal mirror processing methods used today frequently produce mirror surfaces with "locked-in" stresses that eventually lead to expensive surface rework for a finished optical product. This paper focusses on the optical fabrication process where improvements in mirror blank manufacturing can be made which produce stable optical surfaces operable under severe environmental variations for long periods of time.

Over the past five years I have written several programs for hand-held programmable calculators. Most of these programs have dealt with specific technical questions in the fields of optical design and optical fabrication. I have collected these programs in a notebook which is divided into ten sections by catagory. Section names and the individual program titles within each section are given in Table I. No attempt has been made to cover the field of optics or any subtopic thereof. None of these programs were originally written with the idea of publication or sale. I display them as a group on this occasion as a modest example of what can be done to take advantage of the tremendous computational power that has been bequeathed to each of us by the inventors of the pocket calculator.

In-situ testing of large optics greatly increases the speed and accuracy of the figuring process. Rapid test data turnaround and precise contour map displays allow an optician using traditional polishing techniqes to progress rapidly to final figure. At the Optical Sciences Center we have developed a high resolution phase-measuring interferometer that we used during the final figuring stages of a 20-in. diameter, 97-in. focal length off-axis parabola and a 72-in. diameter, f/2.7 symmetric lightweight parabola. Both mirrors were tested and figured in-situ, the off-axis mirror on the table of the swing-arm generator and the 72-in. mirror in a test tower in which the mirror was supported on a rotary table equipped with a polishing arm. High resolution phase maps of each surface were obtained with resolutions of approximately 9mm/pixel and 2mm/pixel on the 72- and 20-in. mirrors, respectively. The phase contour maps were displayed on a video monitor and photographed with a 35mm camera on Tri-X film. The negatives were mounted directly as slides into circular slide mounts and displayed with a slide projector directly onto the slurry coated mirror. The optician then worked the high zones and patches using traditional polishing methods. The circular slide mounts allowed for easy alignment of the contour maps with the fiducialized mirrors. Test turnaround time from one polishing run to the next was about 2 hours allowing for rapid convergence to the final figure.

Free carrier compensation by ion implantation is an important processing technology for the formation of infrared optical waveguides for multiplexing applications. This process leads to a cutoff condition for waveguiding that is wavelength independent. Gallium phosphide is a very attractive semiconductor material for such multiplexing since it is transparent from the visible out to the far infrared. In addition, GaP, together with its related ternary and quarternary compounds, has many of the optical and electronic properties necessary for integration of optical devices into sensing and signal processing circuits. Experiments were performed to characterize the influence of various H+ implantation parameters on the carrier compensation process and to relate the resulting optical effects to electronic changes. The techniques developed for monitoring subsequent temperature processing can be utilized to fabricate optimized optical components.
