| 英文摘要 | The invention describes a laser device comprising at least one laser (10) arranged to emit laser light (12), a light spreading structure (20) arranged to spread the laser light (10) such that an energy density of the spread laser light (22) is reduced in comparison to an energy density of the laser light (12), the laser device further comprising a sensor structure (30) mechanically coupled with a light outcoupling surface of the light spreading structure (20), wherein the sensor structure (30) is arranged to change a physical property in reaction to a change of the reduction of the energy density of the spread laser light (22) in comparison to the energy density of the laser light (12), and wherein the sensor structure (30) is arranged to be coupled to an electrical driver (40) for electrically driving the laser (10) such that the change of the physical property of the sensor structure (30) can be detected by the electrical driver (40) during operation of the laser device. Invention further describes a method of the detecting a malfunction of the laser device. |
