Patent ID: 6853656

Claim:
A laser apparatus ( 1 , 101 ) for use in treatment of skin or mucosa of an animal, including a human being, comprising a laser light emitting optical system for emitting laser light to a surface, said surface being skin or mucosa, the laser light emitting system comprising a laser diode ( 2 , 102 ) emitting a laser beam and a collimating lens ( 3 , 103 ), said collimating lens ( 3 , 103 ) being arranged in the laser light beam path, a power stabilizing system for stabilizing the laser light power within a predetermined power interval, a light wave guide cable ( 10 , 110 ) arranged in the laser light beam path for directing laser light to the surface, and a deflection system ( 8 , 108 ) for deflecting light reflected from the surface away from the power stabilizing system, wherein said collimating lens is arranged between the laser diode and the deflection system.
