The invention is a manual laser device suitably to support the healing of damaged tissues, which is fitted with laser beam source (1), crystal (2), control unit (8), and beam slot (7a, 7b) that is suitable for letting out the beam (4) generated by the laser beam source (1). It is characterized in that it includes a generating coil (5), an insulating layer (6), an ozone generating unit (11) containing a negative electrode (9) and a positive electrode (10), so that the crystal has a bore (3), the control unit (8) is connected to the laser beam source (1) and the generating coil (5), and the ozone generating unit (11) is surrounded by the insulating layer (6).
