The WaterLase Turbo Handpiece operates in a non-contact mode at an optimum distance between 3 to 5 mm from the tissue. The Turbo optical tip creates an energy concentration within a volume extending from 3 mm to 5 mm from the tip’s end at a spot diameter of 500, 700, 900, or 1100 um, depending upon the selected tip type, MX5, MX7, MX9 or MX11. This cylindrical volume defines the optimum cutting region of the laser beam.
