The invention discloses a simultaneous outputting type dual-wavelength hollow laser comprising a planar output coupling mirror (1), a V-shaped conical mirror (2), a positive conical mirror (3), a laser gain medium (4), a plane reflecting mirror (5) and a negative conical mirror (8) that are arranged successively from left to right. A coupling optical system (6) and a semiconductor laser array (7)are arranged right below the plane reflecting mirror (5). The laser gain medium (4), the conical mirror (3), the V-shaped conical mirror (2), the negative conical mirror (8) and the planar output coupling mirror (1) form a laser resonance cavity. The input mirror of the laser resonance cavity is arranged at the right end surface of the laser gain medium (4) and the planar output coupling mirror (1) serves as the output mirror of the laser resonance cavity. According to the invention, the laser outputs the concentric ring beam having the cross section light intensity center with a large dark spot size and the wavelengths of the inner and outer rings of the concentric ring are different, so that the application prospect of the hollow beam is broadened.
