Ti_(3)CN,as a typical hetero-MXene,has attracted tremendous attention for its unique properties.However,its ultrafast photonics applications are still rare.Here,the few-layer Ti_(3)CN MXene was successfully prepared by selective etching and molecular delamination technique.The nonlinear optical response of few-layer Ti_(3)CN MXene at 640 nm was studied using the open-aperture Z-scan technique.The asprepared Ti_(3)CN MXene sample exhibited excellent nonlinear saturable absorption characteristics,resulting in the nonlinear absorption coefficient b of4.05×10^(-2)cm/GW,which was one order of magnitude larger than that of black phosphorus(BP)and molybdenum disulfide(MoS_(2)).For the optical modulation applications of few-layer Ti_(3)CN MXene,passively Q-switched(PQS)solid-state visible lasers based on Ti_(3)CN saturable absorber(SA)at 522 nm,607 nm,639 nm,and 721 nm were successfully realized.Furthermore,a Ti_(3)CN-based stable passively mode-locked Pr:YLF red laser was also successfully achieved with a pulse duration of 30 ps,and the corresponding repetition rate was 73.1 MHz.The optical modulation device based on few-layer Ti_(3)CN MXene shows good performance.Our work demonstrates that the tremendous prospects of the few-layer Ti_(3)CN MXene as a visible optical modulation device in ultrafast photonics applications.

Graphdiyne(GDY),a novel all-carbon nanomaterial,is considered the most easily synthesized and stable carbon allotrope,positioning it as a promising photoelectric material.Herein,we successfully fabricated a high-quality GDY saturable absorber and saturable absorber mirror.Both broadband nonlinear saturable absorption and ultrafast relaxation dynamic properties in midinfrared region of the GDY were investigated.All solid-state diode-pumped short and ultrashort pulsed lasers were realized using the GDY absorber at wavelengths of 2 and 2.8μm,respectively.The results were then theoretically analyzed.This is the first presentation of ultrashort pulsed lasers in the mid-infrared region with GDY absorbers.These results resolutely confirm that GDY could be an optional broadband SA for all solid-state mid-infrared pulsed lasers,and they evidence its promising applications in mode-locked ultrafast lasers.

A highly efficient milli-joule-level Q-switched Tm,La:CaF_(2)laser is experimentally demonstrated.By employing an acousto-optic modulator,the diode-pumped pulsed lasers are stably operated at repetition rates ranging from 500 Hz to 10 kHz.Dual-wavelength operation of 1881.7 nm and 1888.5 nm is achieved with slope efficiency of 64.7%.Up to 1.89 mJ of pulse energy is obtained at a pulse width of 100 ns,corresponding to a peak power of 18.88 kW.These results verified that the Tm,La:CaF_(2)crystal could be a promising candidate for achieving highly efficient and high-energy pulsed lasers.
