40W CO2 surgical laser with fractional handpiece is a high class, modern, ablative laser with comprehensive capabilities in different medical specialties, especially in dermatology and aesthetic medicine. The laser enables work with UltraPulse mode of operation. This high-energetic pulse mode allows the operator to set the value of pulse duration between 100 and 500 µs. The laser emits ultrashort pulse with very high peak power. The work with pulse duration of 200 µs allows the performance of precise ablative treatments with very small thermal damage zone. Work with pulse duration of 300-500 µs extends the thermal damage zone. The frequency of UltraPulse is selected automatically to achieve the desired value of average power.
