The present situation of underwater wireless optical communication at home and abroad is briefly described in this paper. It is pointed out that the blue-green laser communication has the advantages of high concealment, fast speed and small volume. The transmission characteristics of underwater channel wireless light are analyzed, and the source of laser attenuation in seawater is described. According to the system structure,the key technologies and solutions of underwater wireless optical communication are proposed. The efficient adaptive blue green light source, communication link mode and anomalous dispersion optical filter are studied respectively. It provides an idea for the research of wireless optical communication on the underwater.
