Phosphor converted superluminescent diode light source

A light generating system, configured to generate system light, wherein the light generating system comprises a light source, a first luminescent material, and a control system, wherein:

• the light source is configured to generate light source light having a tunable spectral power distribution within a first wavelength range (Λx1);
• wherein the light source comprises a superluminescent diode;
• the first luminescent material is configured to convert at least part of the light source light into first luminescent material light having one or more wavelengths in a first luminescent material light wavelength range (Λm1);
• the first luminescent material is configured such that in an operational mode the system light comprises the first luminescent material light;
• a spectral power distribution of the system light is controllable in dependence of the spectral power distribution of the light source light;
• and
• the control system is configured to control the spectral power distribution of the light source light,
• the light generating system further comprising a color separation element configured downstream of the light source and upstream of the first luminescent material, wherein:
• the color separation element having a wavelength dependent transmission and/or a wavelength dependent reflection within the first wavelength range (Λx1), and;
• the light source, the color separation element, and the first luminescent material are configured such that one or more of the following applies:
• (i) a first part of the light source light is directed from the color separation element to the first luminescent material and (ii) a second part of the light source light is not directed from the color separation element to the first luminescent material, and;
• the light generating system further comprising one or more light combining elements, wherein:
• the light source, the color separation element, and the first luminescent material are configured such that the second part of light source light is directed from the color separation element to one or more of the one or more light combining elements;
• the one or more light combining element are configured to combine the first luminescent material light and the second part of light source light;
• in an operational mode the system light comprises the first luminescent material light and the second part of light source light.
