The device is Fotona LightWalker laser system family (same as K191554). It is based on Er:YAG (2940 nm) and Nd:YAG (1064 nm) laser technology. It combines two flashlamp-pumped laser sources in one housing, with optical cavities containing the Er:YAG and Nd:YAG crystals. A diode aiming beam is combined with both therapeutic laser beams. The combined therapeutic and aiming beams are guided through an articulated arm to an optical handpiece (in the case of the Er:YAG laser), or, in the case of the Nd:YAG laser, through an optical fiber delivery system to an optical handpiece or to the bare fiber distal end. The Er:YAG laser is capable of delivering up to 1.5 J of laser energy in pulses with durations of 50 - 1000 μs and frequencies (repetition rates) of up to 50 Hz. The maximum average output power is 20 W. The laser is intended to be used for incision/excision, cutting, ablation, vaporization and coagulation of soft and hard tissue in dentistry, dermatology and other surgical areas. The Nd:YAG laser is capable of delivering up to 10 J of energy with pulse durations from 0.1-25 ms, and frequencies of up to 100 Hz. For dental indications it is capable of delivering laser pulses with durations of up to 650 μs, frequencies (repetition rates) of up to 100 Hz and a maximum output power of 15 W. The laser is intended to be used for various intra oral treatments in dentistry, and for various surgical and aesthetic applications in dermatology and other surgical areas.
