Abstract Gold nanowires (GNWs) are widely used due to their many excellent properties. Because of their good saturable absorption properties, they can be used in laser mode-locking technology. Using the idea of realizing saturable absorption using its properties of localized surface plasmon resonance (LSPR), the saturable absorber properties of gold nanocrystals and gold nanorod materials were studied, and it was found that they have good saturable absorption properties. In addition, the saturable absorber is the core component of the passive mode-locked fiber laser, and its performance characteristics will greatly affect the output of the laser. By studying the saturable absorption characteristics of GNWs in the 1.56 μm band, it was found that they exhibit good saturable absorption characteristics at the wavelength of 1560 nm, so they can be applied in the laser field.
