Systems and methods for tissue treatment with an asymmetric beam

Abstract

Systems and method for tissue treatment are provided. The systems include an electromagnetic radiation (EMR) source configured to generate a treatment EMR beam, a plurality of optical elements configured to shape and focus the treatment EMR beam to a focal point within a tissue, a window assembly located down-beam from the plurality of optical elements and configured to contact the tissue, and a controller configured to control the EMR source to generate the treatment EMR beam during a treatment procedure. The first axicon and the second axicon are configured to shape the treatment EMR beam such that the shaped EMR beam has a transverse asymmetric energy profile. The plurality of optical elements include a first axicon and a second axicon, and the window assembly is configured to transmit the treatment EMR beam.
