Тонкая пленка Ti₃C₂T_x в качестве насыщающегося поглотителя для пассивной генерации импульсов с модуляцией добротности в резонаторе волоконного лазера, легированного тулием

Мы продемонстрировали волоконный лазер с модуляцией добротности, легированный тулием (TDFL), на основе насыщающегося поглотителя (SA) Mxene Ti₃C₂T_x в качестве модулятора добротности. Ti₃C₂T_x был получен с помощью селективного травления и залит в пленку поливинилового спирта (ПВС). Когда пленка была добавлена в резонатор TDFL, стабильная последовательность импульсов с модуляцией добротности, работающая на длине волны 1996 нм, была получена в одномодовом диапазоне мощности накачки 1552 нм от 161,8 до 237,1 мВт. При изменении мощности накачки в этом диапазоне частота повторения увеличивается с 19,6 до 33,3 кГц, а длительность импульса уменьшается с 6,71 до 3,55 мкс. Насколько нам известно, это первый отчет о Ti₃C₂T_x SA для пассивной генерации импульсов с модуляцией добротности в диапазоне длин волн 2 мкм.
