Abstract

Przedmiotem wynalazku jest sposób kompresji spektralnej krótkich impulsów laserowych swiatla o szerokim widmie, obejmujacy optyczny proces konwersji swiatla w krysztale nieliniowym, przedstawiony na schemacie charakteryzujacy sie tym, ze obejmuje nastepujace etapy: a) impuls laserowy dzieli sie na plytce swiatlodzielacej z wytworzeniem dwóch kopii impulsu swiatla, przy czym b) jedna kopie impulsu swiatla odbija sie od jednej ze stron elementu ze struktura Bragga nadajac impulsowi swiergot zgodny z charakterystyka tego elementu ze struktura Bragga, natomiast druga kopie impulsu swiatla odbija sie od drugiej strony tego samego elementu ze struktura Bragga ze swiergotem nadajac impulsowi swiergot o przeciwnym znaku, a nastepnie c) obydwie kopie impulsu padaja na krysztal nieliniowy, w którym sumuje sie czestosci tych dwóch impulsów swiatla ze swiergotem liniowym i otrzymuje sie zadany waskopasmowy impuls swiatla. Niniejszy wynalazek obejmuje ponadto uklad optyczny do realizacji tego sposobu.
