This paper presents a novel approach to ultrafast laser state active controlling using an anisotropic quasi-1D material, Ta$_2$PdS$_6$. The material's polarization-sensitive nonlinear optical response allows for the modulation of nonlinear parameters in an ultrafast system, enabling the switching between two types of laser states: conventional soliton (CS) and noise-like pulse (NLP). The study demonstrates that by adjusting the polarization of light, the laser can switch between these two states, with both states exhibiting stable performance. Numerical simulations reveal the dynamical processes of CS and NLP states, and digital coding is further demonstrated by using the laser as a codable light source. This work opens new avenues for constructing tunable on-fiber devices and offers a promising method for ultrafast laser state active controlling with low-dimensional materials.This paper presents a novel approach to ultrafast laser state active controlling using an anisotropic quasi-1D material, Ta$_2$PdS$_6$.
