Laser radiation from the cavity can be externally modulated at each wavelength and outputted as an overlapping beam having substantially all the wavelengths produced by the laser elements through a single fiber or as an array of wavelength-separated beams. A modular design facilitates the addition and/or repair of individual or several channels.Other References
