Abstract: Apparatuses and methods are disclosed for applying laser energy having desired pulse characteristics, including a sufficiently short duration and/or a sufficiently high energy for the photomechanical treatment of skin pigmentations and pigmented lesions, both naturally-occurring (e.g., birthmarks), as well as artificial (e.g., tattoos). The laser energy may be generated with an apparatus having a resonator with the capability of switching between a modelocked pulse operating mode and an amplification operating mode. The operating modes are carried out through the application of a time-dependent bias voltage, having waveforms as described herein, to an electro-optical device (e.g., a Pockels cell) positioned along the optical axis of the resonator.

Abstract: In accordance with various aspects of the present teachings, systems and methods for applying treatment energy, e.g., electromagnetic radiation such as laser radiation in the visible and near infrared wavelengths, to body areas having bulges and fat deposits, loose skin, pain, acne and/or wounds. In some aspects, the systems and methods can enable relatively lengthy treatments to be performed by having the practitioner set-up and/or start the treatment, thereafter allowing the treatment to proceed safely and effectively without the continued presence of the practitioner.

Abstract: Methods, systems and apparatus are disclosed for delivery of pulsed treatment radiation by employing a pump radiation source generating picosecond pulses at a first wavelength, and a frequency-shifting resonator having a lasing medium and resonant cavity configured to receive the picosecond pulses from the pump source at the first wavelength and to emit radiation at a second wavelength in response thereto, wherein the resonant cavity of the frequency-shifting resonator has a round trip time shorter than the duration of the picosecond pulses generated by the pump radiation source. Methods, systems and apparatus are also disclosed for providing beam uniformity and a sub-harmonic resonator.

Abstract: Disclosed herein are methods and systems for treatment, such as skin rejuvenation treatment, use non-uniform laser radiation. A high-intensity portion of the laser radiation causes collagen destruction and shrinkage within select portions of the treatment area, while a lower-intensity portion of the radiation causes fibroblast stimulation leading to collagen production across other portions of the treatment area. An output beam from a laser source, such as an Nd:YAG laser, is coupled into an optical system that modifies the beam to provide a large-diameter beam having a nonuniform energy profile, comprised of a plurality of high-intensity zones surrounded by lower-intensity zones within the treatment beam. The higher-intensity zones heat select portions of the target tissue to temperatures sufficient for a first treatment (e.g. collagen shrinkage), while the lower-intensity zones provide sufficient energy for a second treatment (e.g. stimulated collagen production).

Abstract: In part, the disclosure relates to systems and methods for applying treatment energy, e.g., electromagnetic radiation such as laser radiation, to body areas having bulges and fat deposits and loose skin. Methods and systems disclosed herein are surprisingly effective in generating a desirable temperature profile in a target region (e.g., moderate hyperthermia in a range of about 42 to about 47° C.)). Such systems and methods also provide a dynamic balance of heating (via the application of optical radiation to the skin surface) and cooling, while substantially confining treatment temperatures to the treatment region (e.g., at or below the dermal-hypodermal (D/H) junction). In some aspects, systems and methods are provided that simultaneously reduce fatty deposits (e.g., through lipolysis) and tighten the skin (e.g., through the increased production of collagen) while minimizing patient discomfort and unintended damage, for example, within the epidermis and hypodermis regions adjacent the treatment region.
