“…Much the same thing could be realized up in part as to investigating the physics of [119] and [120] of our reference list which would in turn be akin to using [120] of our references as a way to re phrase what we are imagining this problem to be in terms of information theory. It also overlaps with Wald's work as of 1984 as given by [54]. In all, the main end result is to try to avoid the so called black hole bomb effect, where a mini black hole would explode in a laboratory setting within say 10^−16 or so seconds, I.e.…”

Note, that micro black holes last within micro seconds, and that we wish to ascertain how to build, in a laboratory, a black hole, which may exist say at least up to 10^−1 seconds and provide a test bed as to early universe gravitational theories. First of all, it would be to determine, if the mini black hole bomb, would spontaneously occur, unless the Kerr-Newmann black hole were carefully engineered in the laboratory. Specifically, we state that this paper is modeling the creation of an actual Kerr Newman black hole via laser physics, or possibly by other means. We initiate a model of an induced Kerr-Newman black Holes, with specific angular momentum J, and then from there model was to what would happen as to an effective charge, Q, creating an E and B field, commensurate with the release of GWs. The idea is that using a frame of reference trick, plus E + i B = −function of the derivative of a complex valued scalar field, as given by Appell, in 1887, and reviewed by Whittaker and Watson, 1927 of their "A Course of Modern Analysis" tome that a first principle identification of a B field, commensurate with increase of thermal temperature, T, so as to have artificially induced GW production. This is compared in part with the Park 1955 paper of a spinning rod, producing GW, with the proviso that both the spinning rod paper, and this artificial Kerr-Newman Black hole will employ the idea of lasers in implementation of their respective GW radiation. The idea is in part partly similar to an idea the author discussed with Dr. Robert Baker, in 2016 with the difference that a B field would be generated and linked to effects linked with induced spin to the Kerr-Newman Black hole. We close with some observations about the "black holes have no hair" theorem, and our problem. Citing some recent How to cite this paper: Beckwith, A.W.

Fifty years have elapsed from the moment the first light transmitting ceramic‐based commercial item—a sodium vapor‐based street lamp component—reached the market. This paper intends to be a brief chronicle (albeit not a chronology) of this first half century of translucent and transparent ceramic history. The main ceramic materials now available in a transparent state are presented and their main applications are described. Applications range from aerospace and relativistic optics to medical care, supermarket shopping, and modern warfare. Light transmitting ceramics usable as laser gain‐media, armor windows, IR domes, phosphors, scintillators, and electro‐optical components have been developed. The principal achievements this research produced are discussed. Processing strategies for full densification have been devised and quantitative relationships were established between different microstructural features such as amount and size distribution of porosity or level of birefringence, and the level of electromagnetic radiation attenuation they cause. Future prospects list ends the paper.

“…In addition, the wavefront of these optical components is used by the designers and the computational analysts as essential guidance for engineering data control. As a result [3], 1. the beam propagation can be dominated, 2. the optical fabrication processes can be characterized, and 3. the design can be optimized in a meaningful way.…”

“…The wavefront is closely tied to the optical specification of highpower laser systems, such as the national ignition facility (NIF) [1] in the USA and the Shenguang laser facility (SG) [2] in China. As we know, the NIF, a 192-beam high-energy laser, is designed for inertial confinement fusion (ICF).…”

Modal wavefront reconstruction from slope measurements for rectangular apertures

We present a modal wavefront reconstruction from slope measurements for rectangular optical components of high-power laser systems. Wavefront reconstruction with slope data is an important approach used for wavefront control or correction in high-power systems. In this work, we derive a complete set of orthonormal wavefront slope polynomials for rectangular apertures and describe the modal method for obtaining wavefront representation with the aberration balancing property. Error propagation properties for the modal method are evaluated and compared with the Southwell method. The cross-coupling error is also discussed. Numerical experiments are conducted to illustrate that the modal method can achieve a higher accuracy than the Southwell method. In addition, we also investigate the influence of noise on the modal method compared with that of the Southwell method.
