Abstract
A method of spectral beam-combining an array of fiber optics is disclosed. Each fiber may be coupled to a high-power, wavelength-stabilized, fiber-coupled, diode-laser module and has a fiber-by-fiber pre-selected wavelength. The wavelengths may be chosen such that the array can be spectrally combined on, for example a transmission grating and re-focused into an output fiber. This approach is scalable to, for example, 10 kW power and have a beam quality sufficient for metal cutting applications.
