Nonlinear Optical Absorption Properties of Molybdenum Selenide Water Solution.

In recent years, with the invention of graphene, two-dimensional materials have received increasing attention. One of these materials, MXene, has been widely used in the field of photonics and non-linear optics due to its special physical properties. In this paper, the non-linear absorption properties of molybdenum selenide (MoSe2) water solution composites at different wavelengths (500–650 nm) are investigated using Z-scan techniques. The experimental and computational results show that the material has strong saturation absorption (SA) properties and that the SA intensity decreases with the increase of wavelength at the same energy. It has potential application prospects in laser technology. [ABSTRACT FROM AUTHOR]
