BACKGROUND AND OBJECTIVE Laser thrombolysis is a means for clearing blood clots in occluded arteries. Many researchers have studied the mechanisms of clot ablation, and research clinicians have used the technique to treat myocardial infarction with a number of different laser systems. Specifically, a 1-microsec pulsed dye laser has been used clinically to remove blood clots in coronary arteries...

PURPOSE OF REVIEW This article reviews the literature regarding the safety and efficacy of the use of a pulsed CO2 laser for the treatment of vulvovaginal atrophy (VVA). RECENT FINDINGS Prospective observational studies have demonstrated histological changes after the use of pulsed CO2 laser vaginally in atrophic conditions. Increased collagen and extracellular matrix production has been repo...

62 LLE Review, Volume 78 Pulsed laser beams with two-dimensional smoothing by spectral dispersion (2-D SSD), used in inertial confinement fusion (ICF), improve the on-target uniformity on the OMEGA laser system;1–4 however, 2-D SSD is highly susceptible to significant amplitude modulation (AM) during its generation and propagation.5–8 In addition to on-target uniformity, the smoothness of the p...

A laser ultrasonic system has been developed which uses a modulated CW laser source for ultrasonic wave generation. The majority of high frequency laser ultrasonic systems use picosecond pulsed laser sources to generate ultrasound in the hundreds of MHz to the low GHz range. High frequency SAW generation and high-resolution acoustic microscopy require that the generation laser spot be tightly f...

Purpose: To compare the histhologic changes in the retina and chowid, between the continuous and pulsed-wave photocoagulation by diode laser in pigmented rabbits. The r6petitivepulse photocoagulation could prove to be a promising technique for several pathologies in the ocular fundus. Methods: Continuous and pulsed diode-laser transpupillary photocoagulation~ was performed in the eyes of pigmen...

Pulsed lasing from optically pumped rare gas metastable atoms (Ne, Ar, Kr, and Xe) has been demonstrated previously. The laser relies on a three-level scheme, which involves the (n+1)p[5/2](3) and (n+1)p[1/2](1) states from the np(5)(n+1)p electronic configuration and the metastable (n+1)s[3/2](2) level of the np(5)(n+1)s configuration (Racah notation). Population inversions were achieved using...

Objective: To analyse combinational effect of pulsed dye laser and propranolol on treatment of Superficial Hemangioma (SH). Methods: From June 2016 to June 2017, we collected 110 children with SH enrolled in Linyi No.3 People's Hospital. All patients were divided randomly and evenly into two groups (control group and study group). The patients in control group were treated with pulsed dye laser...

A detailed protocol is presented for precisely inserting microscopic objects into the periplasmic region of plant callus cells using laser microsurgery. Ginkgo biloba and Agrobacterium rhizogenes were used as the model system for developing the optical tweezers and scalpel techniques using a single laser. We achieved better than 95% survival after plasmolyzing G. biloba cells, ablating a 2-4-μm...
