摘要:
The invention relates to a dedicated polychromatic light generating device (D). The inventive device (D) comprises optical pumping means (MP) which are used to deliver radiation with at least two different excitation wavelengths (μ1, μ2) and light-guiding means (GL) which are used to deliver polychromatic light at an output (SGL) when excited by the radiation in a non-linear interaction regime.
