Description

technical field

[0001] The invention relates to an all-solid-state laser, in particular to a multi-wavelength narrow-linewidth all-solid-state laser for ocean exploration, the output laser includes 1064nm infrared light, 532nm green light, 355nm ultraviolet light and 486.1 wavelength at the Fraunhofer dark line wavelength of the sun nm blue light. Background technique

[0002] Marine research is of great significance to human development. The seawater light transmission window is in the blue-green band of 450nm to 550nm. Therefore, using the blue-green laser in this band as a light source is an important means of existing ocean laser detection technology and underwater laser communication technology. At present, the most widely used laser light source for ocean exploration is the neodymium-doped yttrium aluminum garnet Nd:YAG laser with an output wavelength of 532nm, and the wavelength is relatively single. The study found that in the deep sea, the attenuation coefficient ...
