Abstract
Optical systems operable to emit multiple frequency-converted spectral peaks are provided. In one embodiment, an optical system includes an optical source and a wavelength conversion device. The optical source may include a laser configured to emit a pump beam having at least two fundamental spectral peaks. The wavelength conversion device may include a non-linear optical medium configured to phase match the second harmonic generation of each of the at least two fundamental spectral peaks and sum-frequency generation of the at least two fundamental spectral peaks such that an output beam comprising at least three frequency-converted spectral peaks having approximately equal power is emitted from an output facet of the wavelength conversion device when the pump beam of the optical source is incident on an input facet of the wavelength conversion device.
