A laser device, in particular for ophthalmological laser surgery, comprising a laser source () for providing laser radiation, controllable scan components () for setting a focus position of the laser radiation, measuring components () for registering information that is representative of an actual position of the radiation focus, and also a control arrangement () controlling the laser source and the scan components. In accordance with the invention, the control arrangement has been set up to bring about the implementation of a test-mode operation of at least some of the scan components with the laser source turned off, in accordance with a predetermined test scan pattern, the test scan pattern defining at least one scan path for the radiation focus, and the control arrangement having been set up to bring about, during a scan movement along the scan path, repeatedly in succession a registration of the actual focus position without stopping the scan movement, and to ascertain a desired focus position, assigned to each registered actual focus position.
