1. A system comprising:
an electromagnetic radiation (EMR) source configured to generate an EMR beam;
a beam shaper configured to collimate and shape the EMR beam into a transverse ring-like energy profile, the beam shaper comprising a first axicon and a second axicon;
an optic configured to converge the EMR beam to a focal region located within a tissue;
a beam scanning system configured to scan the focal region within the tissue; and
a controller configured to pulse the generated EMR beam with a plurality of pulses, wherein at least one pulse of the plurality of pulses has a pulse duration that about 100 microseconds or greater.
