The invention discloses a miniature target heating device for laser dynamic loading experiment. The micro target heating device comprises a target support, a target body, heating elements, a temperature measurement element and a temperature control device. The heating elements and the temperature measurement element are all electrically connected with the temperature control device. Three clampinggrooves are arranged in the target support, the temperature measurement element is clamped in a clamping groove in a middle position, the heating elements are clamped in the clamping grooves in bothsides, and the target body is attached to the back of the target support, a diameter of an inscribed circle of the target body is larger than the diameter of an observation through hole, and a positioning tablet for fixing a target is arranged on the outside the target body. The heating device is a device capable of being used for heating the miniature target body, can heat the target body from aninitial state (300K) to a preset temperature (up to 1000K) in 5 minutes and can control temperature steadily during an experiment through an AI-519 type artificial intelligence adjuster, control precision of temperature reaches 2K, and the device can be used for studying influence of temperature on material damage and fracture characteristic under laser shock loading condition.
