settled state. If a new parameter setting is sent to the laser and dither is off, the laser
will temporarily switch on the tone and switch it off again once settled.
Note : Dither should be disabled only for short periods of time since some
stabilization control loops are disabled causing the laser settings to drift
off. This may cause the output power or the laser frequency to drift away.
In some cases, the laser may become multimode. Switch on dither for a
short period to let the unit settle again.
Note : In some instances, the laser host controller may detect that the laser is no
longer working correctly and may switch on dither automatically in order to
not damage the hardware.
5.5.4.6 Laser on
Button allows switching on and off the Laser. A Pop-up will appear requiring
confirmation if Laser is switched on for Laser safety reasons. This Popup window can
be disabled by editing the .ini File in the Program application directory. This directory
is depending on Windows system path settings.
5.5.4.7 SBS on/off
This button will enable the Stimulated Brillion Scattering Suppression feature for this
laser port. Note that the SBS Frequency needs to be set using the central SBS
frequency button given in the GUI.
5.5.5 Grid
Use this drop down menu to select ITU grids from 25 GHz to 400GHz in order to
allow easily dial in those Frequencies using the rocker switch button control “Laser
Frequency”.
If “None” is selected, any arbitrary Frequency can be adjusted to the laser in 100MHz
increments within available Frequency range.
5.5.6 Set delta Power
This feature allows modifying the output power of all available laser ports at the same
time. Upon activation, it will calculate the maximum change possible for all lasers
based on current setting and available power limits. Dial in a desired value using the
“ΔP” field and click “Set ΔPower” to apply the new value to the “Set New Status”
section.
