1. A method for ablating tissue, comprising:

  • providing a first laser channel,providing a second laser channel, the first laser channel and the second laser channel being coaxial,controlling the first laser channel to detect blood flow in a target via Doppler shift analysis,identifying at least one of desired tissue and undesired tissue in the target in accordance with the blood flow detected via Doppler shift analysis,controlling the second laser channel in response to the Doppler shift analysis to ablate the undesired tissue,whereby topographically complex tissue is precisely excised from the target with minimal blood loss, leaving a sterile surface free of undesired tissue.
