Abstract
Abstract 2D transition metal carbides, nitrides, and carbonitides called MXenes have attracted much attention due to their outstanding properties. However, MXene's potential in laser technology is not explored. It is demonstrated here that Ti 3 CN, one of MXene compounds, can serve as an excellent mode‐locker that can produce femtosecond laser pulses from fiber cavities. Stable laser pulses with a duration as short as 660 fs are readily obtained at a repetition rate of 15.4 MHz and a wavelength of 1557 nm. Density functional theory calculations show that Ti 3 CN is metallic, in contrast to other 2D saturable absorber materials reported so far to be operative for mode‐locking. 2D structural and electronic…
