How can this be? To do that you need megaWatts of power, and you have to focus. The diddy little diode in there certainly won't do that. Also, the dust is on the optics, where the light is not focussed. Also, if there's enough power to burn dust off a lens, then that litte explosion leaves a defect on the glass surface with a lower breakdown threshold, which then gets damaged itself.
