LASER TECHNOLOGIES IN PRODUCTION AND QUARTZ GLASS PROCESSING |
LASER TECHNOLOGIES IN PRODUCTION AND QUARTZ GLASS PROCESSING Brief description: the method of beneficiation of natural quartz material by means of laser radiation can be used in acquisition of quartz grit of high purity which is the initial material for the production of transparent and optical quartz glass (used in optics, illuminating engineering, electronics, chemical industry). Method of glass cutting can be used in electronic, glass, aviation and other branches of national economics for non-waste high quality cutting of fragile non-metallic materials. Originality: the method of benefication of natural quartz material by means of laser radiation gives an opportunity to acquire quartz grit of high purity by means of the processed material control using lasers with different wavelength; method of cutting of quartz glass gives an opportunity to execute thermo splitting of quartz glass of high quality by means of thermo-elastic stress measuring in the area of cutting and by means of dynamical management of technological processing parameters (such as intensity of laser radiation and/or processing speed) which provide the formation of the set rate of thermo-elastic stress in the processed material. Relevance: developments are dedicated to the significant problem solving in the sphere of modern micro- and optoelectronics devices production – development of laser technology used for clearing of quartz grit of high purity and precision processing of quartz glass items. Advantages over analogues: developments give an opportunity to enhance the purity of the quartz grit and to enhance quality and accuracy of laser thermo splitting of quartz glass.
