The anti-misalignment stability and output characteristics of the right angle cone cavity laser are experimentally studied. When the misalignment angle of the cone mirror turns to 46.8 minutes, the single-pulse output energy of the piano-cone cavity laser decreases 24% and the near-field beam patterns have little change; as for the beam directional stability, when the measuring place stands 3.12 m in front of the output mirror, the near-field beam patterns of the piano-cone laser are located at the primary places until the misalignment angle of the cone mirror turns to 18 minutes. These results show that the piano-cone cavity laser has better performances in comparison with the plano-concave cavity laser.The analytical results of the mode instrument are also obtained, which show that the near-field beam intensity distribution of the piano-cone mirror cavity laser is near to the plane wave.
