Physicists have developed a method for drastically narrowing the emission spectrum of an ordinary diode laser, like that in a laser pointer, for use in compact chemical analyzers that can fit into a smartphone, cheap lidars for self-driving cars, as well as security and structural health monitoring systems on bridges, gas pipelines, and elsewhere.
