Ferdinand-Braun-Institut, Leibnis-InstitutfürHöchstfrequenztechnik(FBH) 2021-yil 4-7-oktabr kunlari Berlin-Adlershof shahrida boʻlib oʻtadigan fototexnika kunlari konferentsiyasi va koʻrgazmasida ishtirok etadi.
To'rt kunlik konferentsiya fototonika, optika, mikrotizimlar texnologiyalari va kvant texnologiyalari mutaxassislarini birlashtiradi.

LED nurlanish tizimi ko'p dori-darmonlarga chidamli patogenlar va koronaviruslar bilan kurashadi
FBHUVLED asosidagi nurlanish tizimlarini ishlab chiqdi, ular Charite, Berlin va Greifswald universiteti kasalxonasida sinovdan o'tishga tayyor.

Rekord qiymatlarifordiodelazerlar
FBH kelajakdagi yuqori energiyali qattiq holatdagi lazer tizimlari uchun yuqori takrorlanuvchi nasoslarda o'zining afzalliklariga ega bo'ladi. Institut o'zining diodelazer quvvatini to'rt baravar oshirishi mumkin edi.
FBH optimallashtirilgan diodelazerlarni stack modullariga (yuqoridagi rasm) qadoqlash va optikadagi yaxshilanishlar bilan quradi.
Misol uchun, 780 nm to'lqin uzunligi 1 kW quvvatga ega bo'lgan to'lqinli ulanishli impulsli nasosli nasos birinchi marta 1 mm yadroli tolada (ilgari 1,9 mm) namoyish etildi. Passiv sovutilgan modul ish siklini 20 foizdan (150 ms gacha) 20 foizdan... 50 ms gacha oshirishi mumkin edi.
