Abstract

Apart from the region covered by extremely low frequencies (λ≥3 x 103 km), ocean water is in general very absorptive for electromagnetic radiation, the only exception being the blue-green part of the visible spectrum. Even within this so-called window region, however, losses are high and can range from 0.1 dB/m to 1 dB/m, depending on the water clarity. For purposes of optical underwater communication, ranging, and illumination, powerful blue-green laser sources are therefore required with high efficiency and reliability. This paper discusses some recent progress in the area of blue-green laser technology.
