-The laser system is operated in the MA lab on the 2nd floor. If you want to use the machine, you need the approval of both Prof. Korvink and Prof. Wallrabe. After that you can get the introduction to the machine by the [[equipment|responsible person]]. It is split into two parts, the basic introduction and the introduction into alignment and stitching. Each introduction takes about 1.5h. The introduction notes can be downloaded here:\\+The laser system is operated in the MA lab on the 2nd floor.

-  * The laser needs at least 30-40 minutes to warm up. After about 10-20 minutes it is possible to start lasing, however the machine doesn't have it's full power yet. In order to get to a defined state, you will need to cut for at least 10 minutes into a dummy substrate, just leaving the machine switched on won't do the trick!+  * The laser needs at least 60 minutes to warm up.

   * The laser loses power over time. This can be checked by a reference cut into silicon: The following parameters should cut through a piece of 300 µm Si wafer:\\   * The laser loses power over time.
