De-ionized water
Use de-ionized water to fill the water circuit of the LIMAX
®
120 laser.
The conductivity of this water has to be less than 10 µS/cm.
The laser cooling system consists of a sealed compressor-cooling unit with heat exchanger and
a water circuit to transport the heat from the pump chamber and the power supply unit to the
heat exchanger. The heat exchanger is installed inside the water tank. All in all the water
circuit contains about 3 litres water. The water quality must be very high, because the
pumping light of the laser diode pumping the laser rod goes through it. The water which can be
used is available as car battery or de-ionized water. Fill in 1 litre into the hopper and switch
on the water pump.
