The first menu is used to manually tune the laser modules to a desired wavelength or wavenumber. You
can see which laser module is ready and monitor the require parameters for normal operation.
The user can choose units of either micrometers(μm) or wavenumbers(cm
-1
) in the pulldown menu on the
left. Note how the QCL Tuning Ranges at the bottom will change units too.
The user can now manually tune to a different wavelength:
For example, to tune the laser to 7.75µm on QCL 2, select µm in the pulldown menu, then type in 7.75, then
click the “Tune to 7.75µm” bottom. Once the laser has tuned to that wavelength, the menu will indicate a
green tuned arrow and a check mark.
