Outshining LEDs: Diode Lasers Deliver Intensity to Illumination May 31, 2022 — The development of light-emitting diode (LED) lighting has been a great success story of our times. LEDs are nearly ideal light sources that have largely replaced other lighting technologies, except in some niche applications. Solid-state lighting is now developing in directions such that even the few remaining areas served by discharge lamps will largely adapt to semiconductor-based light sources in the coming years. In practice, laser-diode lighting systems require a complex mix of
