French term or phrase: émission à large spectre
Hello,

"Ces dispositifs de l'art antérieur constituent ainsi des sources de continuum basés sur un pompage extracavité d'une fibre non linéaire. Ils ne permettent cependant pas d'atteindre une émission laser à large spectre présentant une stabilité (ou gigue) temporelle et spectrale suffisante, ce qui rend le rayonnement produit inutilisable pour un certain nombre d'applications."


Please help!
Thank you :)

Broad Spectrum Laser
Explanation:
Voir Wikipedia sous Broad spectrum laser

Most so-called "single wavelength" lasers actually produce radiation in several modes having slightly different frequencies (wavelengths), often not in a single polarization. And although temporal coherence implies monochromaticity, there are even lasers that emit a broad spectrum of light, or emit different wavelengths of light simultaneously.

agree  philgoddard: The question should read "émission laser à large spectre", and your suggested translation isn't very good English - it should be something like "However, they do not allow broad-spectrum laser emissions".
