Mode Window
In HR mode, the laser linewidth is reduced by a factor of 20%. Typically, at
1550 nm, the Normal mode will produce a 1.6 GHz FWHM linewidth, while
the HR mode will produce a 1.4 GHz FWHM linewith. The tuning range (or
power at extreme wavelength) might be smaller in HR mode than Normal
mode.
Selecting the Wavelength Display Unit
To switch between nm and THz as display units, select the corresponding
radio button on the main display.
