The invention provides a quartz capillary microcavity laser temperature measurement system and method, and belongs to the technical field of quartz capillary microcavity laser temperature measurement. The technical problem to be solved is to provide the quartz capillary microcavity laser temperature measurement system structure and the improvement of the temperature measurement method. The technical scheme for solving the technical problem is as follows: the top surface of an upper quartz capillary tube is provided with a fluid channel for adding a gain medium through welding; one side surface of the upper quartz capillary tube is a laser receiving surface, the other side surface opposite to the laser receiving surface is a laser emitting surface, and reflecting films with different refractive indexes are plated on the laser receiving surface and the laser emitting surface; a liquid inlet pipe and a liquid outlet pipe are respectively arranged on two opposite side surfaces of the lower quartz capillary tube;
