Influence of Growth Atmospheres on Characteristics of $Langasite(La_3Ga_5SiO_{14})$ Single Crystals
Langasite( La3Ga5SiO14) is suitable for new piezoelectric properties. Langasite can be applied for communication de-vices due to intermediate piezoelectric properties which are similar to those of quartz and LiTaO3 in its acoustic cha-racteristics. In this study Langasite( La3Ga5SiO14) single crystals were successfully grown by using self-designed Czo-chralski system. From the results of optical properties it was found that crystals having a high quality and higher optical transmittance were grown at atmosphere of 1 to 30 vol% of oxygen content.
Key words: $Langasite(La_3Ga_5SiO_{14})$, Czochralski, Optical Properties
