Abstract

The invention relates to a co-doped upconversion laser system comprising a host-material, whereas the host material is made of at least one crystal material and/ or of a glass material, which features a low phonon energy, whereas said host material comprises a dopant made of Erbium (Er3+), which is pumped by laser light with a single wavelength in the infrared wavelength range, whereas said host material furthermore comprises at least one co-dopant made of Terbium (Tb3+) or Samarium (Sm3+), in order to emit laser radiation in the range of at least one visible wavelength. This system provides a co-doped upconversion laser system featuring an elimination of coulour centres, a reduced re-absorption of the laser radiation and the emission of laser light in the range of visible wavelengths.
