NEODIMIY ARALASHMALI PbMoO4 KRISTALLARIDA AKUSTO-OPTIK XUSUSIYATLARNING ANIZOTROPIYASI
"Maqola"
Sof va neodimiy qo‘shilgan qo‘rg‘oshin molibdati kristallarida [100] va [001] yo‘nalishlar bo‘ylab tarqaladigan bo’ylama akustik to‘lqinlar orqali Bragg yorug‘lik difraksiyasi samaradorligining anizotropiyasi o‘rganildi. Nd konsentratsiyasi taxminan 0,2 mol% edi. Fotoelastiklikning doimiylari va tushayotgan yorug'lik qutblanishining turli yo'nalishlari uchun mos keladigan akusto-optik sifat koeffitsientini aniqlash uchun Dikson usuli ishlatilgan. Akustik to'lqinlarning tezligi ushbu to'lqinlardagi Bragg difraksiyasining burchagini o'lchash orqali aniqlandi. Sof va aralashmali qo'rg'oshin molibdat kristallarida peffva M2ning akustik to'lqinning tarqalish yo'nalishiga va tushayotgan yorug'likning qutblanishiga bog'liqligi ko'rsatilgan.
