Are light and radiation from L.E.D.s ever what laser beams’ light and radiation are?
I had the impression that Light Emitting Diode beams are not the same as Laser beams.

Example quotes from one item:
“Laser whitening or ” POWER WHITENING ” is the latest method developed to whiten your teeth. … the white laser light shone on your teeth will activate the chemical … You can use it as often or as little as you like. … This is the safe simple LED light added to whitening gel.”
I have bought 2 tooth whitening light packages via ebay which I’m unsure about. One states that the light given off is just L.E.D. light. The other is a blue light emitter which looks like L.E.D. lights though it’s stated the light is laser.
Whether or not L.E.D. light whitens teeth, I don’t think these are laser lights. Why would dentists charge £250 for 1 1/2 hours laser whitening? (Ebay sold kits are often less than £10.)
Can L.E.D. light ever be Laser?
I thought L.E.D.s have a specific way of producing light. Is this true? If an L.E.D. were adapted to be a Laser light, as Garret J suggests, would this not mean that the unique L.E.D. light production would be something else (other than the L.E.D. way of producing light)?
