MonaLIGHT: broadband, non-coherent laser-based illumination designed for instrumentation and étendue restricted applications

Description and implementation case study of low étendue, ultra-bright, and non-coherent laser-based light source (1150 lm, 8000 cd) built on a 5W blue LD and YAG based single crystal phosphor for high-efficiency technical applications. The recent development of a new laser-based light source offers enhanced performance and efficiency across various domains, notably in light microscopy, medical procedures, advanced industrial applications, and far-field illumination. This innovative source, with a directional and narrow angle beam, is characterized by its high luminous flux, an impressive luminous intensity exceeding 6000 cd and ability to localize its optical power outperforming any existing LED technology by an order of magnitude. Constructed around a 5 W blue laser diode, laser based light source boasts a compact design and is highly amenable to seamless system integration. Designed explicitly for scientific, biotech, and machine vision applications, it showcases a remarkably low étendue, with 50% of its power concentrated within G ⪅ 0.4 mm2.sr, promising unparalleled system efficiency and the potential to revolutionize optical setups.
