| 摘要 |
<p>The invention relates to a laser (10), especially a rapid-flow, axial-flow gas-transport laser having a processing head (12). In order to prevent damage to the laser (10) in the event of collisions between the laser head (12) and parts which are arranged in the movement range of the laser head (12), and at the same time to make it possible to replace the processing head (12) of the laser (10) easily, the processing head (12) is mounted on the laser (10) by means of a safety coupling (21). <IMAGE></p> |
