Wilfried | Laser | Laser timings adjusted | Since we use the middle window as a reference
for the laser pulse timing, the fact that
the window is 2.25 m behind the target has |

Patrick | Laser | Q-switch window | The solution of increasing the Q-switch window
from 2us to 5us described in [I]ID:148[/I]
fulfills its purpose, but the window is unstable.

third fiber worked best and we could operate
the WM at low exposure times, i.e., below |
