How to Use Auxiliary Functions
Automatic Realignment
Automatic Realignment realigns the laser cavity after Laser Protection. You
should use Automatic Realignment if you have already tried to reactivate
the laser and to reduce power, and this has been unsuccessful.
To realign the laser cavity:
1 Move to the Tunable Laser channel and press Menu.
2 Move to <Realign> and press [OK]. You will see the screen in Figure 81 .
3 Wait approximately 30 minutes. This time depends on how much the
wavelength of the instrument has drifted since the last Automatic Realignment
was performed.

To get the specified performance, ensure that the warm-up time has
passed before starting realignment.
