Method and laser processing device to process tissue. In a general aspect, the method to process tissue may include applying a photosensitizer into an area surrounding a region of the tissue to be processed, and irradiating the region of the tissue to be processed with the pulsed processing laser beam, the laser beam emitting laser pulses with a temporal full width at half maximum in a range between about 100 femtosecond and about 1 nanosecond. In another general aspect, the laser processing device to process tissue may include a laser radiation source to provide a pulsed processing laser beam providing emitting laser pulses, a laser beam decoupling unit to decouple the laser beam towards a region of the tissue to be processed, and an output device to output a photosensitizer in a direction of an area surrounding the region of the tissue to be processed, the output device being connected to the decoupling unit.
1-3. (canceled)
A method for processing a biological tissue, wherein a pulsed laser beam is provided in a processing mode, the method comprising:
The method of claim 1, wherein a repetition rate of the laser pulses is set in a range between about 1 Hz to about 10 MHz.
The method of claim 1, wherein the method is employed for at least one of ablation and removal of a tooth material.
The method of claim 1, wherein the laser beam comprises a substantially rectangular beam profile.
The method of claim 1, wherein the region of the tissue to be processed is scanned by the laser beam.
The method of claim 1, wherein irradiating the region of the tissue to be processed further comprises controlling the laser beam so that a spatial position of a laser beam focus remains on a surface of the region of the tissue.
The method of claim 1, wherein the region of the tissue to be processed is determined in a diagnostic mode.
The method of claim 1, wherein the region of the tissue to be processed is determined by detecting at least one of a presence and a strength of a signal generated in at least one of the tissue and a marker located in an area surrounding the region of the tissue.
