The amplification of a 2 μm concentric vortex beam in a Ho:YAG crystal rod amplifier is simulated and experimentally verified. Different concentric vortex beams are studied and the amplification results are compared with simulation. The integrity of the launched vortex beams is well maintained through the amplification process. Further discussions are provided to increase the gain as well as for power scaling. Due to the nature of Ho:YAG material and the geometry of the rod amplifier, our system shows potential of working as a power amplifier for vortex beams.
