OBJECTIVES To evaluate acute and delayed laser effects of subdermal lipolysis and collagen deposition using an in vivo pig model and to compare histologic findings in fatty tissue after continuous wave diode (CW) vs pulsed laser treatment. METHODS Three CW lasers (980, 1370, and 1470 nm) and 3 pulsed lasers (1064, 1320, and 1440 nm) were used to treat 4 Göttingen minipigs. Following administr...

Direct fabrication of microelectrodes on a polymer substrate using selective ultrashort pulsed laser ablation of inkjet-printed Ag lines" (2012). An inkjet-based ultrashort pulsed laser patterning on a polymer substrate is presented with high-laser scanning speeds. The effects of the laser processing parameters on the ablation characteristics were studied to accomplish damage-free laser ablatio...

Purpose Subthreshold, nanosecond pulsed laser treatment shows promise as a treatment for age-related macular degeneration (AMD); however, the safety profile needs to be robustly examined. The aim of this study was to investigate the effects of laser treatment in humans and mice. Methods Patients with AMD were treated with nanosecond pulsed laser at subthreshold (no visible retinal effect) ene...

Time-resolved imaging, fluorescence microscopy, and hydrodynamic modeling were used to examine cell lysis and molecular delivery produced by picosecond and nanosecond pulsed laser microbeam irradiation in adherent cell cultures. Pulsed laser microbeam radiation at λ = 532 nm was delivered to confluent monolayers of PtK2 cells via a 40×, 0.8 NA microscope objective. Using laser microbeam pulse d...

BACKGROUND Treatment of atrophic acne scars has been limited to the use of such traditional treatments as dermabrasion and chemical peels for many years. Recently, the addition of high-energy, pulsed carbon dioxide (CO2) lasers to the treatment armentarium has created renewed enthusiasm for cutaneous resurfacing due to their ability to create specific thermal injury with limited side effects. ...

Pulsed laser strategies (i.e. pulsed ablation and fragmentation in liquid) have been reviewed with a focus on the synthesis processing of amorphous metal nanoparticles. The possible formation criteria mechanism discussed.

BACKGROUND Several case reports document successful treatment of sebaceous hyperplasia with the pulsed-dye laser. Moreover, noninvasive real-time confocal laser scanning microscopy elucidates the vascular nature of these lesions and their pathophysiologic response to treatment mediated by vessel coagulation. METHODS Ten patients with 29 lesions of sebaceous hyperplasia were treated with 3 sta...

The growth kinetics of the mostly used physical vapor-phase deposition techniques -molecular beam epitaxy, sputtering, flash evaporation, and pulsed laser deposition-is investigated by rate equations with the aim of testing their suitability for the preparation of ultraflat ultrathin films. The techniques are studied in regard to the roughness and morphology during early stages of growth. We de...

In frequency domain laser ultrasonics, the pulsed laser source used for ultrasound excitation in conventional laser ultrasonics is replaced by a low power, amplitude modulated laser source. The acoustic signals are detected using an interferometer or contact transducer, coupled to a RF lock-in amplifier or vector network analyzer. The detection bandwidth reduction afforded by this technique all...

IMPORTANCE Although facial vascular malformations are often treated by facial plastic surgeons, no reliable validated assessment tool exists for surgeons to assess results. OBJECTIVES To use our assessment tool to analyze results from pulsed-dye laser therapy used for pediatric facial vascular malformations, and to determine interrater reliability of our assessment tool in a standard clinical...
