Claim 0:
1. A laser cooling system, comprising:
a first liquid cooled heat exchanger in fluid connection with a first liquid cooled heat exchanger inlet and a first liquid cooled heat exchanger outlet with liquid flowing from the first liquid cooled heat exchanger inlet through the first liquid cooled heat exchanger to the first liquid cooled heat exchanger outlet;
a pair of heat spreaders for mounting a pair of pump diode arrays, the heat spreaders coupled to the first liquid cooled heat exchanger for thermal exchange;
a pair of thermoelectric coolers, each of the thermoelectric coolers providing independent thermal control of one of the pump diode arrays;
a first temperature sensing device mounted on the first liquid cooled heat exchanger to monitor the pair of thermoelectric coolers;
a second liquid cooled heat exchanger in fluid connection with the first liquid cooled heat exchanger by coupling the first liquid cooled heat exchanger outlet to a second heat exchanger inlet and with a second liquid cooled heat exchanger outlet with liquid flowing from the second liquid cooled heat exchanger inlet through the second liquid cooled heat exchanger to the second liquid cooled heat exchanger outlet;
a pair of gain medium, comprising crystals and a pair of crystal mount heat spreaders, the gain medium coupled to the second liquid cooled heat exchanger; and
a second temperature sensing device mounted on the second liquid cooled heat exchanger to monitor the pair of crystal mount heat spreaders;
the first and second liquid cooled heat exchangers being thermally isolated via structure yet sharing a serial fluid path thereby forming a split liquid cooled heat exchanger.
