Wavelength
modulation
The wavelength of the laser can be modulated using either the laser’s internal
function generator or an external signal. From the Settings (gear) drop-down
menu select Wavelength modulation . Depending on the modulation source
selected, Figure 41 to Figure 42 show the Wavelength modulation menus. Within
these menus you can configure multiple parameters that affect the modulation
functionality.
Note: The Settings - Wavelength modulation menu item is only available if the la -
ser includes the wavelength modulation feature.
Modulation Source
The source signal used to modulate the wavelength is selectable. Click on the
Source drop-down menu to select one of three source modes:
•
Internal ( Figure 41 ) – wavelength is modulated using the laser’s internal
function generator
•
External ( Figure 42 ) – wavelength is modulated by connecting an external
signal to the Wav- pins.
