20110059415 | Method and device for laser machining biological tissue - A method of laser machining biological tissue including the provision of a pulsed processing laser beam and the processing of tissue by radiation using the pulsed processing laser beam, wherein the processing laser beam has a wavelength of the laser pulses ranging between 700 nm and 1400 nm, a time duration of the laser pulses ranging between 5 ps and 100 ps, and an energy density of the laser pulses on the surface of the tissue ranging between 1.5 J/cm | 03-10-2011 |
20110183283 | DENTAL LASER TREATMENT DEVICE - Described are a handpiece, a coupling, and a device with a laser source and handpiece for emitting a laser beam for dental treatment. In order to avoid damage to the healthy tooth tissue, an improved determination of the tooth temperature by measurement of at least part of the heat radiation emitted from the treatment area using a temperature sensor, preferably an infra-red sensor, is carried out. Upon reaching or exceeding a temperature threshold, the emission of the laser beam to the treatment area is interrupted or the power output of the laser source reduced or the user made aware of the violation of the threshold value using an acoustic or visual signal. The temperature sensor can be located, e.g., on the handpiece or on the coupling, such as on the coupling tube. | 07-28-2011 |
