controlling a laser power of a laser unit of the rotating laser, using a control or regulating unit of the control and monitoring device, as a function of a rotational speed of a rotating head of the rotating laser;

interrogating the rotational speed of the rotating head and at least one operating parameter of the laser unit using a further control or regulating unit of the control and monitoring device; and

emitting with the further control or regulating unit a signal which influences a laser beam emitted by the laser unit based upon the interrogation.

2 . The method according to claim 1 , wherein the at least one operating parameter is at least one of a laser power setting made by the control or regulating unit, and an operating parameter of the laser unit designed as a laser power emitted by the laser unit.

3 . The method according to claim 1 , further comprising:

activating a blocking and/or deflection unit of the control and monitoring device to block or deflect the laser beam emitted by the laser unit, as a function of the at least one signal emitted using the further control or regulating unit.

4 . The method according to claim 1 , wherein at least one of the at least one signal is a function of the at least one operating parameter of the control or regulating unit.

5 . The method according to claim 1 , wherein:

a sensor signal of a movement sensor of a sensor unit of the rotating laser is interrogated using the control or regulating unit;

interrogating the rotational speed of the rotating head comprises interrogating a sensor signal of a further movement sensor of the sensor unit; and

an operating mode defined by a rotational speed and/or by a rotation direction, of the rotating head, is determined as a function of an evaluation of a temporal change of the sensor signals interrogated by the control or regulating unit and the further control or regulating unit.

6 . The method according to claim 1 , wherein at least one voltage characteristic variable, of an operational amplifier, of the laser unit is interrogated by using the further control or regulating unit to emit, using the further control or regulating unit, at least as a function of the at least one voltage characteristic variable of the operational amplifier, the at least one signal influencing the laser beam emitted by the laser unit.

7 . A control and monitoring device for a rotating laser, configured to control a laser power of a laser unit of the rotating laser as a function of an operating mode of a rotating head of the rotating laser, comprising:

at least one control or regulating unit configured to control the laser power of the laser unit as a function of a rotational speed of the rotating head; and

a further control or regulating unit configured to interrogate, independently of the control or regulating unit, the rotational speed of the rotating head and at least one operating parameter of the laser unit, and to emit a signal that influences a laser beam emitted by the laser unit based upon the interrogation.

8 . The control and monitoring device according to claim 7 , further comprising:

a connection unit connecting the further control or regulating unit, using control or regulation technology, to the laser unit to interrogate the at least one operating parameter of the laser unit.

9 . The control and monitoring device according to claim 7 , further comprising:

a blocking and/or deflection unit configured to block and/or deflect the laser beam emitted by the laser unit, which blocking and/or deflection unit is activated by the signal emitted by the further control or regulating unit.

at least one laser unit with at least one rotating head, with at least one drive unit configured to drive the rotating head; and

at least one control and monitoring device according to claim 7 .

11 . The rotating laser according to claim 10 , further comprising:

a sensor unit comprising at least two movement sensors which are different from one another and which are arranged on the drive unit or on the rotating head and configured to detect a rotational speed of the rotating head.
