NKT Super K FIANIUM Compact Tunable Laser
=========================================
The NKT Super K service contains software for controlling both the `NKT SuperK FIANIUM Supercontinuum White Light Laser <https://www.nktphotonics.com/products/supercontinuum-white-light-lasers/superk-fianium/>`_
and the `NKT SuperK VARIA Variable Bandpass Filter <https://contentnktphotonics.s3.eu-central-1.amazonaws.com/SuperK-VARIA/SuperK%20VARIA%20Product%20Guide-%2020231016%20R1.3.pdf>`_.
This is done because a single open port to the device is needed that cannot be shared between multiple services.

Associated drivers for both the FIANIUM and VARIA also need to be installed.

.. note::
   There is a separate service for the NKT SuperK EVO.

Datastreams
-----------
``emission``: Output emission of the FIANIUM (int) - 0 is OFF, 3 is ON.

``power_setpoint``: Output emission power level of the FIANIUM (in percent).

``pulse_picker_ratio``: Pulse picker ratio for the FIANIUM.

``monitor_input``: Monitors the input to the VARIA from the FIANIUM.

``nd_setpoint``: Set point for the VARIA ND filter.

``swp_setpoint``: Upper bandwidth limit for the VARIA (in nm).

``lwp_setpoint``: Lower bandwidth limit for the VARIA (in nm).

``nd_filter_moving``: Whether the ND filer is moving for the VARIA.

``swp_filter_moving``: Whether the short wavelength (high-pass) filter is moving for the VARIA.

``lwp_filter_moving``: Whether the long wavelength (low-pass) filter is moving for the VARIA.
