“…However, there is atmospheric turbulence in reality. It makes the atmospheric attributes change random and continuously [5] [6] [7], thus it influences the received signal inevitably. The change of optical wave attributes caused by medium change should be taken into consideration so as to detect the target accurately.…”

In order to study the transmission characteristics of laser in atmospheric turbulent medium and understand the influence degree of various factors on amplitude fluctuation, by means of smooth perturbation method, this paper establishes a theory model of amplitude fluctuation of laser propagation in turbulent medium by using the smooth perturbation method and reflects the amplitude fluctuation degree, carries out specific discussion on each influence factor. The results show that the larger the wavelength, the more stable the amplitude fluctuation. With the increase of laser section radius, the amplitude fluctuates sharply and then decreases slowly after reaching the peak. Transmission distance is the main influence factor of amplitude fluctuation. With the increase of transmission distance, the amplitude fluctuation will become more obvious. The amplitude acquisition can be comprehensively modulated in a specific transmission distance by wavelength and section radius, so as to ensure the stability of the received laser and provide a theoretical basis for the interferometry technology.
