A system is provided for generating a blue-green optical signal with a wavelength in the range of 450-550 nm and corresponding to a Fraunhofer line, comprising: a plurality of laser diodes, each laser diode generating a first optical signal having a first wavelength, lambda ; a plurality of optical fiber, each optical fiber having a first end optically coupled to receive the optical signal from one of the laser diodes and a second end for emitting a second optical signal having a second wavelength, lambda /2, where the wavelength lambda /2 corresponds to a Fraunhofer line, the second ends forming a fiber optic bundle for emitting a composite optical signal comprised of each of the second optical signals; a servo-controlled gimbal for supporting the fiber bundle to direct the direction of the composite optical signal; and a computer operably coupled to provide direction control signals to the servo-controlled gimbal.
