An LED and a semiconductor laser (or laser LED) work in essentially the same way, that is, light is emitted as electrons and holes combine, with emission wavelength dependent upon the materials used.

Instead it has an intrinsically narrow beam angle. “The Dragon Dome [SFH 4783] is the first high-power infrared LED that emits its light within an angle of +/-12°,” said Osram. “From a current of 1A, ...
