Mazkur ishda nanosoniy davomiylikdagi impulsli-davriy lazer nurlanishi ta’sirida almaz, rux oksidi va titan dioksidning mikrostrukturalangan kukunlarining optik xossalarini eksperimental tadqiq etish natijalari keltirilgan. Xona haroratida o‘rganilgan namunalarda Raman sochilishi va fotolyuminessensiya spektrlarining shakllanish mexanizmlari tahlil qilindi. Ikkilamchi nurlanish intensivligining lazer impulsi energiya zichligiga bog‘liqligi aniqlandi. Mikrostrukturalanish elektromagnit maydonning lokal taqsimotiga sezilarli ta’sir ko‘rsatib, nolinear effektlarning kuchayishiga va spektral xususiyatlarning o‘zgarishiga olib kelishi ko‘rsatildi. Olingan natijalar sensor tizimlar, fotokatalitik qoplamalar va funksional optik materiallarni ishlab chiqishda qo‘llanishi mumkin.
