This study presents an approach for active control of ultrafast laser states using anisotropic quasi-1D material Ta₂PdS₆ as a saturable absorber. The material's polarization-dependent absorption enables modulation of nonlinear parameters in ultrafast systems, allowing for the generation of two laser states: conventional soliton (CS) and noise-like pulse (NLP). The laser state can be switched in a single fiber laser through polarization control, with numerical simulations revealing the dynamic processes of these states. Digital coding was demonstrated using the laser as a codable light source. The work proposes a method for ultrafast laser state active control using low-dimensional materials, offering new possibilities for constructing tunable on-fiber devices. Ta₂PdS₆, a ternary van der Waals material with high air stability, exhibits anisotropic optical properties and broadband photoresponse. Its band gap varies with thickness, enabling wideband absorption in the infrared regime. The material's anisotropic structure provides an additional degree of freedom for light modulation through polarization control, offering opportunities for tunable optoelectronic devices. Ultrafast fiber lasers based on Ta₂PdS₆ were constructed by integrating the material precisely in the fiber end face. The material's polarization-dependent saturable absorption was investigated using an all-fiber twin-detector configuration. The results showed that the saturation intensity and modulation depth depend on the tilt angle of the polarization controller. The material's high modulation depth (over 31%) makes it suitable for use as a saturable absorber for ultrafast pulse generation. The Ta₂PdS₆-based ultrafast fiber lasers were able to generate both CS and NLP states. The CS state produced ultrashort pulses with a pulse width of 697 fs and a pulse energy of 2.62 nJ, while the NLP state produced pulses with spike widths as short as 98 fs. Both states exhibited long-term stability and were characterized by their noise features and spectral properties. The NLP state showed a more pronounced spectral broadening than the CS state. The study demonstrated the ability to switch between CS and NLP states by adjusting the polarization controller's tilt angle. The results showed that the NLP state had a higher threshold for stable operation compared to the CS state. The NLP state also exhibited a higher timing jitter than the CS state. The study further demonstrated the potential of the Ta₂PdS₆-based ultrafast fiber laser for digital coding applications, with the ability to encode optical binary codes of NUDT (010011100101010100010001010100).
