Abstract
A sensor device for determining a physical value using a laser, whose emission behavior can be affected by the physical value is described. The laser is arranged to emit at least two concurrent modes lying above a laser threshold and the physical value is determined using a comparison of changes of the at least two modes occurring under the influence of the physical value.
