Abstract: A system includes a focus optic configured to converge an electromagnetic radiation (EMR) beam to a focal region located along an optical axis. The system also includes a detector configured to detect a signal radiation emanating from a predetermined location along the optical axis. The system additionally includes a controller configured to adjust a parameter of the EMR beam based in part on the signal radiation detected by the detector. The system also includes a window located a predetermined depth away from the focal region, between the focal region and the focus optic along the optical axis, wherein the window is configured to make contact with a surface of a tissue.

Abstract: A method includes generating a plurality of primary beams from a laser beam, and generating, from a primary beam one or more secondary beams. The method also includes focusing the first secondary beam to a first focal region in the target tissue and the second secondary beam to a second focal region in the target tissue. The first focal region and the second focal region can be located at different depths in the target tissue.

Abstract: Systems provided include an electromagnetic radiation (EMR) treatment device configured to generate a treatment EMR beam to treat a patient tissue afflicted with a condition. The EMR treatment device is operable at a set of base parameters. The system also includes at least one processor, and at least one non-transitory computer-readable storage medium storing instructions thereon. The instructions, when executed by the at least one processor, cause the at least one processor to receive patient data from a remote network in electronic communication with the at least one processor, determine one or more recommended changes to the set of base treatment parameters based on the received patient data, offer the determined one or more recommended changes to a treatment operator, and append the patient data with at least one posttreatment image of the patient tissue. The patient data includes at least one pretreatment image of the patient tissue.

Abstract: An optical system includes an array of optical elements configured to receive a primary laser beam and generate a plurality of sub-beams. The array of optical elements includes a plurality of optical elements that are configured to simultaneously focus the plurality of sub-beams to a plurality of focal regions in a target tissue. A pitch of the array of optical elements ranges from about 1 mm to about 3 mm. A numerical aperture of one or more optical elements of the plurality of optical element ranges from about 0.3 to about 1. A first sub-beam of the plurality sub-beams is configured to generate plasma in a first focal region of the plurality of focal regions.
