The invention relates to a full air-cooled end pump laser which comprises a laser element device and a laser pump source, wherein the full air-cooled end pump laser also comprise a laser resonant cavity for holding the laser element device and a pump cavity for mounting the laser pump source in separate arrangement; the laser resonant cavity and the pump cavity are in detachable connection; the laser resonant cavity comprises a first outer cavity, an inner box body which is arranged inside the first outer cavity and is used for holding the laser element device, and a first constant-temperature unit which is arranged inside the first outer cavity and is in adjacent arrangement with the inner box body; and the pump cavity comprises a second outer cavity, the laser pump source arranged inside the second outer cavity body, and a second constant-temperature unit which is arranged inside the second outer cavity and is in adjacent arrangement with the laser pump source. The full air-cooled end pump laser can respectively and accurately control the temperature of a working environment of the laser resonant cavity part and the pump cavity of the laser pump source, and is convenient to maintain and repair.
