| 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. |
| 其他摘要 | 本发明描述了一种激光装置，包括至少一个用于发射激光（10）的激光器（10），一个光扩散结构（20），用于扩散激光（10），使得扩散激光的能量密度（与激光（12）的能量密度相比，减小了图22），激光装置还包括与光扩散结构（20）的光输出耦合表面机械耦合的传感器结构（30），其中传感器结构（与激光（12）的能量密度相比，30）被设置为响应于扩散激光（22）的能量密度的减小的变化而改变物理性质，并且其中传感器结构（30） ）被布置成耦合到电驱动器（40），用于电驱动激光器（10），使得传感器结构（30）的物理特性的变化可以由电驱动器（40）在操作期间检测到。激光装置。本发明还描述了一种检测激光装置故障的方法。 |
