Abstract: A laser including a semiconductor laser stack group, a beam compositor, a pump beam collimator, a thin-disk laser crystal, a first and a second parabolic reflectors with the same facial contour function, a corrective reflector, an output mirror, and a jet-flow impact cooling system. The thin-disk laser crystal and the output mirror form a laser resonant cavity. The first parabolic reflector, second parabolic reflector, thin-disk laser crystal, and corrective reflector form a multi-pumping focus cavity. The jet-flow impact cooling system is used for cooling the thin-disk laser crystal. The pump light produced by the semiconductor laser stack group is composited by the beam compositor, collimated by the pump light collimator, and enters the multi-pumping focus cavity. Within the multi-pumping focus cavity, the pump light is focused, collimated, and deflected to converge on the thin-disk laser crystal. The laser resonant cavity produces and outputs a laser beam.
