Free Space Optics (FSO) is an optical communication technology where free space acts as a medium between the transceivers. In FSO as the light signal is transmitted through the atmosphere so it is essential to take weather conditions into consideration. In this paper, the performance of free space optics link is analyzed using homotopy perturbation method and investigated under different weather conditions by optimizing the beam divergence. In the designed system the optical source used is continuous wave (CW) laser with optical signal power of 40 mW. The signal with operating wavelength of 850 nm is transmitted in free space, experiences attenuation due to weather conditions such as rain, snow, fog. It is analysed that smaller beam divergence improves the performance of the system..
