Abstract

Eye-safe, low-power-density, Class 1 or Class 3R laser treatment systems for medical applications are disclosed. Systems having controlled power and stray irradiation can meet laser safety requirements according to IEC 60825-1:2007 or equivalent for eye-safe rating; classification as laser-Class 1 or as laser-Class 3R. Laser system comprises a diode laser source, an optical fiber probe, means for detecting and identifying said optical probe and means to ensure that laser power transmitted from the fiber probe is limited to pre-specified maximum power level per application; laser wavelength; emission characteristics; probe characteristics; limiting values according to applied safety regulations. Device can identify the connected optical fiber probe to exclude using non-conforming optical fiber probes and/or to limit maximum output to optical powers in compliance with laser safety regulations. System preferably operates at a wavelength of 1400 nm or higher. Breakage or leakage from fiber probe is detectable and prevented.
