    摘要: An exemplary treatment system can be provided which can include a laser system configured to emit at least one laser beam, and an optical system configured to focus the laser beam(s) to a focal region at a selected distance from a surface of a tissue. The focal region can be configured to illuminate at least a portion of a target. The optical system can cause an irradiation energy transferred to the focal region of the laser beam(s) to (i) generate a plasma in a first region of the tissue adjacent to the target, and (ii) avoid a generation of a plasma in a second region of the tissue. The optical system has a numerical aperture that is in the range of about 0.5 to about 0.9. An exemplary method can also be provided to control such treatment system.
