Researches on underwater transmission characteristics of blue-green laser

Considering the scattering and absorption caused by seawater molecules and suspended particles, the characteristics of blue-green laser in seawater are described. Then a transmission model of blue-green laser in shallow seawater is established and the relations of the attenuation of received power and the requisite transmission power to the transmission distance are summed up. Results of the simulation experiment are obtained and it can provide references for engineering estimation.
