Spletfluence with large number of pluses is better because it does not damage the surface (Matsui 2002). In the case of continuous laser, the scanning speed influences the efficiency of the laser cleaning process and the time of cleaning. Under high speed and low speed scanning by laser, the surface might not be cleaned and get damage respectively. Spletcaused by a laser in a muscle phantom was calculated to be 8.4 J maximum over 80 seconds. This corresponds to a fluence (energy per unit area) of 0.105 J/cm2 per 1 s.
