A bacteria removal laser is provided, especially for removing caries bacteria from natural or prosthetic teeth, the prosthetic teeth also being treated via extraoral approach, having a gripping handle, a laser radiation source, an application optics having a predetermined radiation exit surface, especially a radiation guide rod through which laser radiation passes, and an energy source such as a mains connection or an accumulator. The laser emits in the wavelength range between 2200 nm and 4000 nm and is especially designed as an Er:YAG laser. The energy output averaged over time is less than 1 mJ/mmat the radiation exit surface.

Bacteria removal laser

A security feature has a plurality of luminescent surface elements, wherein luminescence lifetime varies between the surface elements. In order to verify the security feature, a lock-in imager is used. The security feature is illuminated with excitation light, which is intensity-modulated with a modulation frequency. The luminescent light emitted by the security feature is detected synchronously with the modulation frequency in a plurality of pixels. This is used to determine a measure of a phase shift between the excitation light and the luminescent light in different pixels. The security feature is verified taking account of the measure of the phase shift in different pixels.
