The paper establishes a transmission model for Laguerre-Gaussian vortex beams in atmospheric turbulence that is affected by finite-amplitude acoustic waves (i.e. non-linear waves). This study examines the variations orbital angular momentum (OAM) properties of beam disrupted waves. It also explores effects source parameters, namely pressure amplitude and frequency, on spiral spectrum detection probability. results indicate impact OAM varies depending distance wave transmission. Moreover, characteristics become more pronounced with higher frequency. solely impacts extent variation refractive index structure constant, while frequency associated not only constant but distribution constant. Hence, can be intentionally modified employing various models.
