laser headlighs on cars

Each headlight features a laser module that generates a cone of light that reaches twice as far as Audi’s LED headlight. Each module sports four laser diodes just 300 micrometers in diameter. They fire a blue laser beam with a wavelength of 450 nanometers into a phosphor converter, generating white light with a color temperature of 5,500 Kelvin–the perfect white light for nighttime illumination. The laser spot, as Audi calls it, supplements the standard LED high beam at speeds over 38 mph. A camera detects pedestrians and cars ahead and adjusts the beam so you don’t blind them.

anyone know details?what power diodes they use?
