We demonstrated a Q-switched thulium-doped fiber laser (TDFL) based on Mxene Ti3C2Tx saturable absorber (SA) as Q-switcher. Ti3C2Tx was obtained using selective etching and embedded into polyvinyl alcohol (PVA) film. As the film was added into a TDFL cavity, a stable Q-switched pulse train operating at 1996 nm was produced within a single mode 1552 nm pump power range from 161.8 to 237.1 mW. When the pump power was varied within this range, the repetition rate increased from 19.6 to 33.3 kHz while the pulse width decreases from 6.71 to 3.55 µs. To the best of our knowledge, this is the first report of a Ti3C2Tx SA for passively generating Q-switched pulses in the 2 µm wavelength region.

Мы продемонстрировали волоконный лазер с модуляцией добротности, легированный тулием (TDFL), на основе насыщающегося поглотителя (SA) Mxene Ti3C2Tx в качестве модулятора добротности. Ti3C2Tx 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 Ti3C2Tx SA для пассивной генерации импульсов с модуляцией добротности в диапазоне длин волн 2 мкм.
