In this paper we report a number of studies of the propagation of the Laser Integration Line (LIL) and Laser Megajoule (LMJ) beams when interactions happen with optical components
defects. These research are mainly achieved on a numerically predictive foundation with the CEA MIRO beam propagation code.
It observes the LODTM following error and generates a correction sign that adaptively removes any cyclic following error. The DECS controller was originally developed for dither management of telescope IR secondary mirrors. (The Keck telescope and another observatory telescopes use this system.) The specific DECS algorithm is not discussed in the paper, as it's a proprietary algorithm of LM, however, the results of applying this expertise to the LODTM is offered within the paper. Together, both of these methods have reduced the LODTM place following error to the required micro-inch tolerances.

The reduction of following error by this method proved very profitable and is reported in the paper. Method two makes use of an adaptation of a proprietary controller developed by the Structural Dynamics group of the Lockheed Martin Corporation (LM). The system, know as the DECS controller, works along with the current LODTM control system.
Scratches on the floor of fused silica optics may be detrimental for the performance of optical techniques because they initiate injury on the optic but in addition they perturb the amplitude or section of the transmitted laser mild. Removing scratches by conventional sharpening techniques could be time consuming as it is an iterative and lengthy process, especially when hours of polishing time are required to obtain very high surface accuracy. The silica is then heated at temperature higher than the softening level to heal the cracks. The main subject of software of Tydex's large optics
is astronomy and relevant applications. Moreover, many optical parts are produced to complete varied illumination, scanning, and lidar techniques, laser techniques, and testing methods having utilized significance and intended to solve research and engineering issues.
The flaws that we thought of are located at the entrance or rear floor of the optical parts. These surface flaws correspond to engineered defects corresponding to scratches and to floor damage resulting from laser-induced progress process, from mitigation course of or from goal interactions particles. Results account for the attainable downstream impacts of flaws at the rear-floor of the optics and from one part to a different along the laser chain. In explicit, the influence on the LIL/LMJ finish-of-line focal spot depth and size is predicted.
The following error reduction has been shown even at comparatively excessive disturbance frequencies with respect to the servo system bandwidth. Applying these two strategies to the LODTM, the machine control system following error is lowered to a stage that now not contributes to half contour error. With primarily no management system error, extra process points and machine error sources have been recognized.
