Abstract
The invention provides a light generating system () comprising a light generating device (), a luminescent material layer (), and optics (), wherein: (I) the light generating device () is configured to generate polarized laser radiation (); (II) the luminescent material layer () comprises a luminescent material () configured in a light-receiving relationship with the light generating device () and configured to convert at least part of the polarized laser radiation () into luminescent material radiation (); (III) the light generating system () is configured to generate in an operational mode system light () at least comprising the luminescent material radiation (); (IV) the optics () comprise first optics () and second optics (); wherein the first optics () are configured to change the polarization of the polarized laser radiation (), and wherein the second optics () have one or more of (i) a polarization dependent transmission and (ii) a polarization dependent reflection for the polarized laser radiation (); and (V) the light generating device () and the optics () are configured such that, relative to an optical path of the luminescent material radiation () emanating from the luminescent material (), the second optics () are configured downstream from the first optics () and the luminescent material ().
