ABSTRACT:
A laser system has a laser which can be switched between at least two power settings and an energy supply unit for the laser, with the supply input voltage applied at said energy supply unit being mains voltage. The present invention is distinguished by the energy supply unit having a distribution unit at whose input connection main voltage is applied and which is connected to a laser power unit and a charge unit for an accumulator unit in such a manner that during the time that the laser is operated with low power the charge unit is also supplied with energy from the electric mains in addition to the laser power unit and that during the time that the laser is operated with high power the output connection of the accumulator unit is connected to the laser power unit.
