The present invention relates to a laser device for supporting work on a construction site and a laser beam detector for detecting light of a laser beam rotating around a rotation axis of a laser device. There is a need that the detector is able to identify the laser device which emitted the light that the detector detects. This can be achieved by a laser device comprising a laser unit configured to emit a laser beam; an optical element arranged to rotate the laser beam around a rotation axis; and a transmitter configured to transmit a communication signal over an interface to a receiver of a laser beam detector, wherein the communication signal provides information about a rotation pattern of the rotating laser beam.

Laser device and laser beam detector for detecting light of a laser device

The application relates to indicating a grade for example in constructions applications using a laser beam. A laser beam is emitted from a laser unit to a desired direction having a grade angle with regard to a level angle. The level sensor is provided for adjusting the level angle and a grade sensor is provided for indicating a grade angle on the basis of the level angle from the level sensor.
