The utility model discloses a cryogenic coaxial laser instrument of taking through built -in thermistor, including the radiator base, still include hot electric refrigeration ware, hot electric refrigeration ware bottom surface is the face of heating and fixes with radiator base top surface, and the top surface of hot electric refrigeration ware is the refrigeration face and fixes with the heat sink bottom surface of passing through, and the heat sink top surface that passes through is the grooved surface with coaxial laser instrument tube appearance adaptation, and coaxial laser instrument tube sets up on grooved surface, and the inner wall of coaxial laser instrument tube is provided with thermistor. Hugging closely thermistor and the laser tube core chip, reducing external thermal resistance in the laser instrument through the transition of structural inseparable laminating is heat sink, the at utmost has reduced temperature control system's target temperature error. Avoided the dear butterfly area of use price refrigeration laser instrument tube, assembly process is simple, will take temperature control's laser instrument material cost and the very big degree of cost of labor to reduce.
