In order to obtain a miniaturization and light weight solid-state laser

the diode pump cooling system need to reduce its weight

a solution based on Al Cu combinated heat sink with thermoelectric coolers is proposed. The software Flotherm is used to optimize the design of heat sink

and then verify the cooling system in the actual use of the environment. The experimental results show that the designed scheme meets the requirements of solid-state laser cooling demand

the weight loss design of the pump module cooling system has been carried out.
