Abstract
A laser system may include a semiconductor laser configured to emit laser radiation in continuous wave operation at M modes having differing angular frequencies, where 2≤M and where n=[1; M]. A tuning apparatus may periodically modify the angular frequencies where a variation of each angular frequency is smaller by at least a factor of 2 than a mode distance between the relevant adjacent angular frequencies. A detector has an upper cutoff frequency which is smaller by at least a factor of 10 than the smallest of the mode distances. A beam splitter may guide the M modes each to the detector and to an object, such that the detector may detect, for each of the M modes, portions of the laser radiation reflected by the object and portions of the laser radiation which come optically directly from the semiconductor laser.
