Flexible temperature controller for laser non-linear crystal

The utility model provides the technical scheme of a flexible temperature controller for a laser non-linear crystal. The scheme is that the controller comprises a temperature control base, a non-linear crystal arranged on the temperature control base, a holding cover, an upper flexible heat release unit, and a side flexible heat release unit. The holding cover is fixed on the temperature control base. The upper flexible heat release unit is arranged inside the holding cover and is in contact with the top surface of the non-linear crystal. The side flexible heat release unit is arranged between the holding cover and the temperature control base and is in contact with the side surface of the non-linear crystal. The scheme combines a thermo-compensation principle and a flexible heat release principle, thereby effectively improving the comprehensive performance of thermal impact resistance and vibration resistance of the non-linear crystal, ensuring the stable and reliable holding of the laser non-linear crystal in the large temperature difference and vibration environment, and solving the problem of temperature and vibration environment adaptability of a laser in the large temperature difference and strong vibration environment.
