Abstract

Sposób wytwarzania światłowodu aktywnego prowadzącego i generującego promieniowanie o długości fali ? obejmuje etap wykonania subpreformy rdzenia ze szkła domieszkowanego domieszką aktywną, oraz etap wyciągania subpreformy rdzenia wraz z preformą płaszcza. W etapie wykonania subpreformy rdzenia zestawia się preformę strukturalną zawierającą przynajmniej pręty szklane, wykonane ze szkła pierwszego rodzaju o pierwszym współczynniku załamania (n1) oraz pręty szklane drugiego rodzaju o drugim współczynniku załamania (n2). Pręty te układa się według wybranego wzoru dla zapewnienia założonej charakterystyki współczynnika załamania. Drugi współczynnik załamania (n2) jest wyższy lub równy najwyższej wartości charakterystyki współczynnika załamania założonej dla rdzenia, zaś pierwszy współczynnik załamania (n1) ma wartość mniejszą lub równą najniższej wartości założonej charakterystyki współczynnika załamania w przekroju poprzecznym rdzenia. Szkło drugiego rodzaju zawiera przynajmniej jedną domieszkę aktywną. Preformę strukturalną poddaje się pocienianiu przez wyciąganie dla uzyskania subpreformy rdzenia. Wymiary prętów oraz parametry procesu wyciągania preformy strukturalnej i subpreformy rdzenia z płaszczem dobiera się tak, by pocienione w wyniku wyciągania pręty szklane stanowiące podłużne elementy rdzenia gotowego światłowodu miały wymiary poprzeczne mniejsze od 1/5 długości fali ?. Aktywny światłowód jest przystosowany do prowadzenia i generowania promieniowania o długości fali ?. Jest on wyposażony w płaszcz oraz rdzeń zawierający przynajmniej jedną domieszkę aktywną, znamienny tym, że rdzeń zawiera podłużne elementy ze szkła pierwszego rodzaju o pierwszym współczynniku załamania (n1) oraz podłużne elementy ze szkła drugiego rodzaju o drugim współczynniku załamania (n2) zorientowane wzdłuż światłowodu i tworzące zwartą wiązkę, przy czym wymiary poprzeczne podłużnych elementów rdzenia są mniejsze od 1/5 długości fali ?.
