摘要
Two-dimensional materials have extensively promoted the development of ultrafast photonics in the past decade. In our work, the saturable absorption properties of ZrSe2 were presented. The saturation intensity, modulation depth, and nonlinear absorption coefficient of the ZrSe2 saturable absorber (SA) are about 13.14MW/cm(2), 6.09%, and 1.85 * 10(-1) cm/GW. In the experiment, based on the ZrSe2 SA, two types of solitons were recorded. A conventional soliton with a pulse width of 985 fs and a three-pulse bound state soliton have been obtained. Our experiment reveals that ZrSe2 can be employed for generating multiple ultrafast soliton generations and possess promising application in ultrafast photonics. (C) 2020 Optical Society of America.
