According to one embodiment of the present invention, a frequency-converted laser source is provided wherein the wavelength conversion device comprises a plurality of waveguide components comprising respective input faces positioned in an effective focal field of the laser source. Individual ones of the waveguide components contribute different elements to a set of distinct wavelength conversion properties, defining a set of distinct wavelength conversion properties attributable to the waveguide components. The set of distinct wavelength conversion properties comprises properties representing phase matching wavelengths of the waveguide components, spectral widths of the waveguide components, conversion efficiency of the waveguide components, or combinations thereof. Additional embodiments are disclosed and claimed.
