What is a white laser?

Explaining the mechanism of broadband coherent light sources generated by nonlinear optical effects.

This article explains the principles and applications of white lasers. Unlike conventional white light sources (LEDs and halogen lamps), white lasers are characterized by their ability to generate broad-spectrum and coherent light. Focusing on the supercontinuum method, which is obtained by passing ultrashort pulse lasers through nonlinear media, we will clearly introduce the generation mechanism, main application fields (such as communications, medical, precision measurement, and LiDAR), and the challenges in commercialization.
