AVA is the equivalent of AVAILABLE (see below), if Coherence Control is on or
below Uncal level.
AVAILABLE indicates that the set value is too high for laser output while the
instrument is warming up.
The value given in the message is the maximum power available.
CC UNCAL indicates that the set power value is too small to achieve full
linewidth broadening.
EXC is the equivalent of EXCESSIVE (see below), if Coherence Control is on or
below Uncal level.
EXCESSIVE indicates that the set value is greater than the laser can output at
this wavelength.
The value given in the message ( P= ) is the actual power being output, the
maximum power available at that wavelength.
INITIALIZING is displayed while the instrument is performing its internal
initialization.
LASER PROTECTION indicates that the laser has been switched o to prevent
damage to the laser diode.
Try, once or twice, to reenable the laser. If this does not work, try reducing the
power, and then reenabling. If this does not work, press 4

Realign for
Automatic Realignment. This will automatically realign the laser cavity. See
\Automatic Realignment" in Chapter 3 for more information.
STABILIZING indicates that the laser heat chamber is not at operating
temperature. It can take around 1 hour for the temperature to stabilize.
The percentage value given as part of the message indicates how close the
