1. A light source, comprising:
a laser operable to emit laser light at a wavelength in a range from 460 nanometers to 470 nanometers;
a laser light wavelength stabilizer that comprises an active loop control with a loop control circuit that stabilizes the laser at an absorption wavelength of Eu3+ ions; and
a converter assembly arranged to convert the laser light to photoluminescent light having a longer wavelength than the laser light,
wherein the converter assembly comprises a converter element doped with Eu3+ such that under irradiation of the laser light the converter assembly emits photoluminescent light in a red spectral range.
