Operation II: Remote Mode

For the remote mode to work, the lasers must be connected to the interlock box, the interlock system must be engaged and the laser key turned on as described above. The lasers can then be controlled through the MEDM GUIs:

To turn a laser on:

1. Set the desired temperature and current in the ``Set Temp'' and ``Set Current'' enter boxes.
2. Press the ``Enable'' button. If you have a camera pointing at the laser box in the Hall then you should see 'laser enabled'.
3. Press the ``Start'' button. If you have a camera pointing at the laser box in the Hall then you should see 'laser on'. The laser should now be on.

To turn a laser off:

• Press the ``Stop'' button. If you have a camera pointing at the laser box in the Hall then you should see 'laser disabled'.

In addition to cameras pointing at the lasers boxes in the Laser Hut to monitor lasers on or off, there is a spectral-analyzer which monitors both the relative power and the waveform of the lasers. The spectral-analyzer has remote readback. Alarm will be set when the readback deviate from the regular running condition by more than $10\%$. This will enable us to know when there is one laser goes off or when the cell ruptured.
