The invention discloses an air-cooling and condensation integrated device for a laser of a pulse xenon lamp pump and belongs to the technical field of cooling and condensation of lasers of pulse xenon lamp pumps. A semi-elliptical reflecting surface is formed in the middle of the lower end surface of an upper cooler of the device; cooling fins for cooling are arranged on other end surfaces, except the lower end surface, of the upper cooler; a first round-bottom reflecting mounting groove and a second round-bottom reflecting mounting groove are formed in the upper end surface of a lower cooler; cooling fins for cooling are arranged on other end surfaces, except the upper end surface, of the lower cooler; the lower end surface of the upper cooler covers the upper end surface of the lower cooler in an aligned manner, and the upper and lower coolers are fixedly connected through two connecting cover plates, so that the axis of the first round-bottom reflecting mounting groove and the axis of the second round-bottom reflecting mounting groove are located in two focus axes of the semi-elliptical reflecting surface respectively. By the aid of the device, the solid laser of the pulse xenon lamp pump can be air-cooled, and a cooling and condensation system of the laser is miniaturized.
