Tm-doped mode-locking fiber lasers with 2D chromium telluride (CrTe2) materials as saturable absorbers
In this paper, the nonlinear optical (NLO) properties of two dimensional (2D) CrTe2-materials in 2 μm were investigated, obtaining with a modulation depth of 6.5% and a saturable intensity of 42 MW/cm2, respectively. By using CrTe2 as a saturable absorber (SA) and operating in a Tm-doped fiber laser system, a stable fundamental mode-locking laser with the pulse width about 0.96 ps and central wavelength of 1907.2 nm has been achieved. Furthermore, multi-pulses and harmonic mode-locking operations also been observed, which indicating the potential of CrTe2 SA in pulsed laser applications.
