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.

According to the invention, the intermediate sheath (13) is formed by assembling longitudinal elements (13A) and includes: a first optical material, the refractive index of which differs from the refractive index of the monomode core by at most 10 -3 ; and a second optical material, the refractive index of which is lower than the refractive index of said monomode core and differs therefrom by at least 10 -3 .
摘要:
The subject of the invention is a supercontinuum source capable of emitting waves between the infrared range and the ultraviolet range, comprising a pulsed laser source (12) capable of generating a laser beam and a non-linear microstructured optical fibre (14) capable of receiving said laser beam, in such a way that the supercontinuum source is capable of generating a beam (F') over a pulse duration (T'), characterized in that the supercontinuum source includes means for varying said pulse duration.
