摘要：
The spot profile and intensity distribution of output beam from unstable resonator of a DF Laser were measured. The results showed the spot was a ring with 45mm external diameter and the measurement data sufficed for the design requests. But the spot was asymmetric seriously on horizontal direction, which was arose by two possible reason, one was non-uniform distribution of the gain medium, the other was the optic-axis migration to upstream of gain medium.
