configure the laser. The set command will set all parameters shown to the according
laser. All parameters dialed in will be automatically coerced to the minimum or
maximum value permissible.
Available Parameters are:
5.5.4.1 Laser frequency
Use this button to dial in frequency to be used by laser. This control is automatically
coerced to maximum and minimum possible frequency.
Note : If Laser is currently operating at a different frequency, Laser light will be
shut off for tuning process. A warning window appears before the
operation is executed. If you require continuous tuning, refer to the Fine
tuning feature described below
5.5.4.2 Fine tuning (FTF)
This option allows deviating Laser frequency from initial set value. As opposed to
“Laser frequency” tuning, the Laser remains switched on during tuning and keeps
optical specifications stable. Furthermore, relative tuning granularity is superior over
“Laser frequency” tuning.
Note : If Laser was previously set using the “Laser frequency” option, Fine
tuning will be temporarily disabled for a few seconds to let the laser
stabilize before fine tuning can be performed.
5.5.4.3 Output Power
This control allows configuring output power of Laser. Control coerces to available
power range.
5.5.4.4 Tuning state (Current status only)
Tuning state indicates whether a laser port is currently tuning. A red light indicates
tuning activity while a grey color indicates the devices is settled and has achieved its
optical performance.
5.5.4.5 Dither on/off
This option is available only for special versions of the laser. It Dis or enables a
carrier frequency dither tone applied to the laser line which is used to keep the laser
frequency fixed to a given setting. The dither tone may be disabled if the laser is in a
