The table explains the technical parameters for the dosage of laser energy and treatment time used in this case report. GaAlAs – Gallium Aluminum Arsenide Diode; GaAs – Gallium Arsenide Diode. The two diodes are part of a single laser system, the Multiwave Locked System (MLS). For patients with dark skin color, there is a pigment adjustment selection button on the laser console. When the pigment selection is activated, laser intensity is reduced by 50% and the software automatically recalculates the required dose.
