Extended theory of selective photothermolysis
A new theory of selective thermal damage of non‐uniformly pigmented structures in biological tissues is presented and limitation of the pigment temperature and heat diffusion from the pigmented to the targeted areas is proposed.
Contact cooling of the skin.
A computational model that describes contact precooling of a multilayered skin structure prior to laser irradiation of a cold plate made of material with a high thermal conductivity is developed and experimentally verified.
The role of laser tunnels in laser‐assisted lipolysis
Laser‐assisted lipolysis (LAL) devices are used as adjuncts to liposuction that create laser tunnels to heat the adipose and connective tissue. Available systems vary significantly across choice of
Compact 1J mid-IR Cr:ZnSe Laser
We report a record output energies of pulsed Cr:ZnSe lasers operating at 2.65 um. The maximum output energy of the Cr:ZnSe laser was demonstrated to be more than 1.1 J for 7 ms pulses.
Evaluation of cooling methods for laser dermatology
Skin cooling is used to protect the epidermis in a variety of laser dermatology procedures, including leg vein treatment, hair removal, and port wine stain removal. Spray and contact cooling are the
Lattice of optical islets: a novel treatment modality in photomedicine
A majority of photothermal applications of laser and non-laser light sources in medicine (in particular, in dermatology) are based on the paradigm of (extended) selective photothermolysis. However,
Characterization of an optimized light source and comparison to pulsed dye laser for superficial and deep vessel clearance
An arc lamp‐based device providing optimized spectrum and pulse shape was characterized and compared with two pulsed dye laser (PDL) systems using a vascular phantom. Safety and effectiveness for
Semi‐Automated method of analysis of horizontal histological sections of skin for objective evaluation of fractional devices
This report describes an innovative and efficient method of processing and evaluating horizontal sections of skin using a novel software program to evaluate the damage profiles generated by fractional devices.
Evaluation of a fractional laser with optical compression pins
Micro‐beams of a 1,540 nm laser are co‐aligned with optical pins in a device designed to provide skin compression during treatment to remodel the deeper reticular dermis and hypodermis while minimizing epidermal damage.
Self-adaptation Optical Effects in Photothermal Treatment of Skin Structures
Photothermal effects form basis for many uses of optical energy to treat various medical conditions. With an increase in the optical power density, thermally induced phase transitions and chemical
