“…In addition, the twist phase, a specific type of phase different from the usual quadratic phase, can only exist in partially coherent beams and was first highlighted by Simon et al [15]. Due to its unique characteristics, considerable research has been devoted to studying light beams carrying the twist phase [16][17][18][19][20][21][22][23][24][25][26][27][28][29]. It was found that the beam rotates during propagation, beyond the classical Rayleigh limit, which effectively reduces beam scintillation and causes its orbital angular momentum to be driven by the twist phase [17,18,25,27].…”

“…Unlike previous complex methods [27], the most recent methods can not only truly generate twisted partially coherent beams, but also simplify the steps. Based on the aforementioned research, several twisted partially coherent beams with special spatial correlation structures have also been proposed and generated [28,29]. It was show that the twist phase will induce the rotation of the degree of coherence of a twisted partially coherent beam on propagation and influence the spectral degree of polarization distribution.…”

“…On the other hand, as laser beams serve as the primary medium for optical communication, it is very important to study their propagation characteristics in the presence of atmospheric turbulence [2,3,29,[35][36][37][38][39]. In comparison to coherent beams, partially coherent beams offer more possibilities to mitigate the adverse effects caused by turbulence [2,3,29,36]. Furthermore, the twist phase and the cross phase can further enhance the turbulence resilience of partially coherent beams [18,37].…”

In this letter, we conducted a detailed investigation of the statistical properties, such as spectral density, spectral degree of coherence (SDOC), orbital angular momentum (OAM) flux density, and propagation factor M2, of a twisted Gaussian Schell-model (TGSM) beam carrying the cross phase in a turbulent atmosphere. Our findings revealed that atmospheric turbulence induces degeneration of the intensity distribution and spectral degree of coherence of a Gaussian Schell-model beam with the cross phase during propagation, while the twist phase acts as an antidote to degradation. Furthermore, we observed that the z-component of the time-averaged angular momentum flux is determined by the twist phase, whereas the cross phase influences the distribution of the OAM flux density in the beam. Additionally, we explored the variations in the propagation factor M2 of a TGSM beam with the cross phase in a turbulent atmosphere. Notably, we discovered that the deleterious effects of the atmospheric conditions can be mitigated by modulating both the twist and the cross phases. This work contributes valuable insights for information transfer and optical manipulations.
