A semiconductor laser apparatus combined with a chromophore and a method for using them in treating hard tissues, such as for example dental tissue, in which elements (3) for applying a chromophore in the area of the tissue to be treated are coupled to a semiconductor laser (4), elements for conveying (5, 6) the laser light and for focusing (7) the laser light on the tissue to be treated also being coupled to the laser; the chromophores can be chosen among different chromophorous agents and must have a high coefficient of absorption at the wavelength of the laser chosen for the type of treatment and/or tissue to be treated.
L'invention concerne un appareil laser à semiconducteurs combiné à un chromophore, ainsi qu'un procédé d'utilisation de ceux-ci dans le traitement de tissus durs tels que par exemple du tissu dentaire. Dans cet appareil, des éléments (3) destinés à appliquer un chromophore dans la zone de tissu à traiter sont reliés à un laser à semiconducteurs (4) et des éléments destinés à transporter (5, 6) la lumière laser et à focaliser (7) cette lumière laser sur le tissu à traiter sont également reliés au laser. Les chromophores peuvent être choisis parmi différents agents chromophores et doivent posséder un coefficient d'absorption élevé à la longueur d'onde du laser choisi pour le type de traitement et/ou le tissu à traiter.
