Picosecond Nd:YAG versus Fractional CO2 Lasers in Management of Postburn Scars

Plastic and Reconstructive Surgery, Global Open
Background:. The picosecond laser was primarily designed to enhance tattoo removal. Because it has a new innovative mechanism for energy delivery, it has been modified to be used in other conditions such as skin resurfacing, which was usually treated ...

Evaluation of Combined Treatment With Picosecond Laser and Acoustic Shock Wave Therapy for Tattoo Removal: A Prospective Randomized Controlled Trial

JEADV Clinical Practice
Background Laser tattoo removal traditionally employs q‐switched and picosecond lasers, which require multiple sessions. Besides the selective photothermolysis that laser devices offer, the photoacoustic effect by acoustic pulse devices may provide ...

Alopecia Totalis Treated with 1064 nm Picosecond Nd:YAG Laser: A Case Report

Applied Sciences, 2019
Alopecia areata (AA) is an autoimmune disorder causing nonscarring hair loss. Alopecia totalis (AT), the severe form of AA, is usually refractory to many first-line treatments including topical and intralesional corticosteroids and topical immunotherapy.

B-integral limitation of ultra-high-peak-power lasers

High Power Laser Science and Engineering
In the design and construction of ultra-high-peak-power laser systems, it is necessary to control the accumulated B-integral of the laser pulse, but currently there are no reasonable B-integral control standards for picosecond and femtosecond lasers.
