Abstract: A dental laser assembly is disclosed for use in eradicating carious lesions in teeth, the treatment of sensitive teeth, as well as the removal of soft tissue, the incising of the frenum, opurculum, anesthesia of the tooth, etching enamel for restorations or orthodontic appliance fixation, the welding of fixed prosthesis, removal of bacterial flora periodontal pockets, removal and/or vaporization of healthy or necrotic pulp, the vertical and/or horizontal condensation of gutta percha or any other root canal sealant, the cauterization of blood vessels in the oral cavity, vaporizing bone tissue, removing tartar, apical fusion of foramina, enlarging and shaping root canal, removing carbon from surface of teeth, removal of enamel, bleaching teeth, etching dentin, separating orthodontic brackets, merging hydroxyapatite to bone and enamel, amalgam removal and undercutting of carious and/or healthy dentin and/or cementum. The laser assembly includes a housing having a cavity in which a pulsed laser is contained.

Abstract: A dental laser assembly is disclosed for use in eradicating carious lesions in teeth, the treatment of sensitive teeth, as well as the removal of soft tissue. The laser assembly includes a housing having a cavity in which a pulsed laser is contained. The laser is excited so that the laser emits a laser beam along a predetermined axis that is in line with a fiber optic delivery system and at a pulse rate of one to 10,000 pulses per second and an average power variable from zero to 50 watts. A handpiece is dimensioned to be inserted into a human mouth while an optical fiber optically connects the laser output to the handpiece. The laser assembly also includes a continuous output aiming laser which, upon activation, provides a continuous laser aiming beam coaxial to the treatment beam. Both beams are then introduced into a fiber optic delivery system.

Abstract: Disclosed is a laser spot projector for use with a laser coagulation system in which a laser beam is radiated as a focussed spot into a portion selected to be thermally coagulated. A laser source produces a laser beam, and a focussing lens focusses the laser beam on the selected portion in the form of a focussed laser beam spot. A variator lens is displaceably arranged between the laser source and focussing lens for changing the magnification of the laser spot depending upon the displacement of the variator lens. The variator lens is selectably displaceable to two separate positions where the image point is conjugated with the object point with respect to the variator lens. This arrangement makes it possible to selectably provide two focussed laser beam spots each having a different spot diameter.

Abstract: A laser coagulation system adapted for use in an ophthalmological treatment comprises a slit image projector for projecting a slit image into the eyeball of a patient to determine a selected portion of the eyeball to be coagulated, and a laser beam projector for projecting a laser beam onto the selected portion. Both the projectors include a common reflecting means which is divided into two side portions for directing slit light toward the selected portion to be coagulated, and a central portion between the two side portions for directing the laser beam toward the selected portion thereof.
