Abstract : A method of emitting on a specific wavelength Fraunhofer line of peak seawater transmission and minimum solar radiation is disclosed. This method includes the steps of emitting at least on a specific wavelength of an infrared transition line from a neodymium gain element in an optical resonator; frequency tripling the infrared line from the resonator to a specific ultraviolet wavelength in a frequency multiplier; and Raman down shifting the specific ultraviolet wavelength a predetermined degree by a predetermined number of Stokes shifts in a predetermined medium in a Raman shifter to produce a high peak-power output at the specific wavelength Fraunhofer line.
