摘      要：Alloying in two-dimension has been a hot spot in the development of new,versatile systems of optics and *** have been demonstrated to be a fascinating strategy to modulate the chemical and electronic properties of two-dimensional *** firstly reported ultra-broadband enhanced nonlinear saturable absorption of Mo0.53W0.47Te2 alloy at 0.6,1.0,and 2.0μ*** nonlinear saturable absorption of Mo0.53W0.47Te2 saturable absorber(SA)was measured by the open aperture Z-scan *** to MoTe2 and WTe2 SAs,the Mo0.53W0.47Te2 SA showed five times deeper modulation depth,8.6%lower saturable intensity,and one order larger figure of ***,our research provides a method of alloys to find novel materials with more outstanding properties for optics and optoelectronic applications.
