1. A method of treating a target tissue comprising:
generating, using a laser source, an output beam having a subnanosecond pulse duration;
modifying the output beam, using an optical system, to provide a photomechanically disruptive treatment beam;
directing the photomechanically disruptive treatment beam to one or more regions of dermal pigmentation;
photomechanically disrupting the one or more regions of dermal pigmentation; and
decreasing visible appearance of the dermal pigmentation in response to the treatment beam.
