摘　　要：过渡金属硫代亚磷酸盐MnPS3是三元含磷二维材料,具有新颖的光电特性.采用化学气相传输方法生长MnPS3单晶,结合机械剥离方法制备可饱和吸收体光纤调制器件.以MnPS3可饱和吸收体构建掺铒光纤环形激光器,实现脉冲间隔为196.1 ns,脉冲宽度为3.8 ns,最高输出功率为27.2 mW,1565.19 nm和1565.63 nm双波长锁模脉冲激光输出,实现280 h以上高稳定自启动双波长锁模输出.As a member of the metal phosphorus trichalcogenide family,MPS3 is widely used in nonlinear optics and devices,which can be regarded as a significant benefit for the excellent photonic and optoelectronic properties.In this work,the MnPS3 nanosheet is prepared by the chemical vapor transport method and the MnPS3 saturable absorber is demonstrated by modifying mechanical exfoliation.To the best of our knowledge,the dual-wavelength self-starting mode-locking erbium-doped fiber laser with MnPS3 saturable absorber is demonstrated for the first time.The dual wavelength mode-locked laser with a pulse repetition rate of 5.102 MHz at 1565.19 nm and 1565.63 nm is proposed.Its maximum output power at the dual-wavelength is 27.2 MW.The mode-locked laser can self-start and stably run for more than 280 h.
