The present state of laser glasses production for optoelectronic systems and devices is considered. The limitations of existing laser glasses and the necessity to create new ones have been viewed. The urgency of the development and introduction of new types of laser glass for its use in both civilian and defense equipment sectors is shown. The technological complexity of the phosphate erbium glasses production is substantiated. The purpose of the work is to create laser glasses and make a laser element, will be operating wavelength of 1.54 μm. Optimum concentration of rare earth oxides in laser glasses has been determined. The quality control methodology and technology of laser glasses were developed. The production of a new laser glass makes it possible to use it in modern optoelectronic systems. The laser elements were fabricated and their generation characteristics were investigated. The results of the laser elements industrial testing are presented.

Control Methodology

This chapter is based on the very real experience of a flood in one of the repositories of Barcelona's Municipal Archive, introducing a quality control methodology for the air-drying of wet documents. It is a simple monitoring system that allows you to quantify the degree of drying during treatment. The data derived from it will help reduce intervention to a minimum, optimizing resources, reducing losses and minimising the risk of mould formation. Disaster Plans include many possible scenarios. Because of their vast scope they cannot contain detailed practical information that would be helpful for those who have to intervene. All the steps of the process are reported here, from the choice of the most suitable methodology (forced airing through plastic mesh ventilation) to the completed stabilization of the holdings. The goal is to inform the reader of the measures adopted at each stage, providing practical advice.

The design, analysis, and control methodology of an energy efficient and high force to weight ratio rare earth N42 NdFeB based permanent magnet linear oscillating motor has been described. For this axial flux machine the mover is consisting of Aluminium structure embedded with rare earth permanent magnets of high energy density. Microcontroller based drive is developed for frequency and thrust control of the machine. Finite element method using FEMM is employed for analysis of various performance parameters of machine. The same parameters are also compared with the measured ones, which yields a good agreement to the proposed design.
