The invention discloses a high-performance double-tail-end pumping single-doped Ho:YAG solid laser, relates to a solid laser, and aims at solving the problem that the existing single-doped Ho laser easily causes unbalanced heat distribution in the crystal so as to cause bad influence on high-power operation of the laser. The high-performance double-tail-end pumping single-doped Ho:YAG solid laser is characterized in that the pumping mode is double-tail-end pumping, both two paths of pumping lights need to penetrate through an isolating device firstly, and then are filled into the single-doped Ho:YAG crystal; the pumping lights enter respectively from a 0-degree 2mum total reflection mirror and a 45-degree 2mum total reflection mirror; a resonance cavity of the laser is arranged by a first total reflection mirror, a second total reflection mirror and a 2mum output coupling mirror according to an L-shaped structure; and the 2mum output coupling mirror obtains 2mum single-wavelength laser for outputting by tuning the angle of an F-P (Fabry-Perot) etalon. The high-performance double-tail-end pumping single-doped Ho:YAG solid laser is used for obtaining 2mum single-wavelength laser.
