Configuring Wavelength/Frequency or Delta Temperature
Configuring Wavelength/Frequency or Delta
Temperature
Values appearing on the display correspond to:
³
the actual value obtained in Normal or Dither Modulation modes at
selected wavelength
OR
³
the delta temperature (difference between the above value and the
temperature obtained after switching to High Wavelength Stability or
On/Off Modulation modes).
Adjustable parameters depend on the control mode:
³
Normal and Dither modes: to adjust the spectral value (wavelength or
frequency). Relative value is only available for these modes.
³
High Wavelength Stability and On/Off Modulation modes: once you
have set the wavelength in Normal mode or Dither, you can use these
modes to enhance wavelength stability at the established value
(permitted tuning range: ±1 °C).
³
In all modes, modifying the wavelength or frequency also modifies the
internal laser temperature. The source will then take a few seconds to
adjust to the new value.
