Mode-locked thulium-doped fiber laser with chemical vapor deposited molybdenum ditelluride

A passively mode-locked thulium-doped fiber (TDF) laser was realized by employing chemical vapor deposited few-layer molybdenum ditelluride (MoTe ) as a saturable absorber (SA). The few-layer MoTe film was transferred onto the waist of a microfiber and then incorporated into a TDF laser with a typic...

Description
Summary:A passively mode-locked thulium-doped fiber (TDF) laser was realized by employing chemical vapor deposited few-layer molybdenum ditelluride (MoTe ) as a saturable absorber (SA). The few-layer MoTe film was transferred onto the waist of a microfiber and then incorporated into a TDF laser with a typical all-fiber ring cavity configuration. Stable soliton pulses emitting at 1930.22 nm were obtained with a 3 dB bandwidth of 4.45 nm, a pulse duration of 952 fs, and an average power of 36.7 mW.
