This is all backwards.
The main reason the typical Rubidium box needs a serious heat sink is that
there is an active heater inside it heating up the lamp to get it up to
operating temperature. That part of the system better be "tolerant" of high
(enough) temperature.
... or a less heat-producing alternative could be used. The
Rubidium-lamp produces two wavelengths of which one is filtered by a
Rubidium-filter which leaves the final pumping wavelength. This is what
a laser diode could supply instead.
Maybe things would be a lot better/simpler if the heating/cooling we have
been discussing were split into two sections. One for the lamp assembly, and
a second for the electronics.
Most of the discussion has been on thermal isolation of the entier
units. Not what needs generates temperature and what requires
temperature stability etc.
Anybody know what the thermal coefficient of the lamp is relative to the
electronics?
I am not sure I know what you mean by this...
Cheers,
Magnus
