ABSTRACT:
An optical wavelength converter device is of the fiber type including a cladding and a core surrounded by the cladding, the cladding having a lower refractive index than the refractive index of the core. The optical wavelength converter device serves to convert a fundamental wave into a secondary harmonic wave. The cladding has an exit end surface shaped for converting the wavefront of a wavelength-converted wave from the conical wavefront into a planar or spherical wavefront. A optical wavelength converter system comprises such an optical wavelength converter device and an optical device for diffractively or refractively converting the wavefront of the wavelength-converted wave from a conical wavefront into a planar or spherical wavefront.
