Abstract

In this work the nonlinear optical characteristics of sand glass which is the origin of quartz crystal were evaluated, sand glass particles from mining site waste were prepared by washing, drying, magnetic separation and sieving. The particles are soaked in sulphonic acid H2 SO4 acidic solution with 30% concentration for 100 hours, the new compound with optical characteristics was formed at different volume fractions of sandglass such as 20%,40%,60%, and 80% respectively. The new machine was developed for manufacturing the new compound from sand glass. The optical nonlinear absorption coefficient of the sand glass-ceramics material was investigated using the Z-scan technique, provided with nanosecond pulses of second harmonic (green Nd:YAG laser with 532nm wavelength). The effect of lattice structure and particles concentration on the non-linear optical properties were also discussed. The conclusions and recommendations for the best material and concertation for nonlinear optical material were mentioned. The research end with conclusions and recommendation for the development of new optical materials based on micro and nanoparticles from natural resources.
