Posterior capsular opacification Yag laser PCIOL Pupil Visual acuity Cataract is one of the most leading cause of curable blindness all over world. In the developing word most popular method of cataract operation is extra capsular cataract extraction (ECCE) with posterior chamber into ocular lens in plantation eye (PCIOL) by Various Methods. This hold true for our county and Rajasthan state too...

BACKGROUND To report the negative effect of Nd: Yag (Neodymium-doped: Yttrium Aluminium Garnet) laser capsulotomy on the intraocular pressure (IOP) and the trabeculectomy bleb integrity, in a small series of eyes, both trabeculectomised and pseudophakic, following the laser application for the management of posterior capsular opacification (PCO). METHODS This is a retrospective, non-comparati...

In this paper, spectroscopic analysis (OES) for copper (Cu) plasma was achieved at atmospheric pressure. Q switched Nd: YAG pulsed laser with a fundamental wavelength (1064 nm), energy range (500-800) mJ, frequency (6 Hz), and pulses (10-30 pulses) applied to induce plasma. Based on the analysis, parameters like electron temperature (Te), density (ne), Debye length (?D), (fp) have been calculat...

In this paper, we report results of n2 measurements of new chalcogenide glasses in the Ge–Sb–S–Se system using a modified Z-Scan technique. Measurements were made with picosecond pulses emitted by a 10Hz Q-switched mode-locked Nd-YAG laser at 1064nm under conditions suitable to characterize ultrafast nonlinearities. The nonlinear index increases up to 500 times the n2 of fused silica with an in...

BACKGROUND Axillary hyperhidrosis is a common but difficult-to-treat condition with major social, labor, and emotional consequences. OBJECTIVE The aim of this study is to present the Nd-YAG laser as a safe and effective option for the treatment of axillary hyperhidrosis. MATERIALS AND METHODS From January 2002 to April 2007, 17 patients (15 women and 2 men) with axillary hyperhidrosis were ...

In recent years, great attention has been paid to high peak power all-solid-state pulsed blue-green lasers [1–4] for some applications such as spectroscopy, display, optical data storage, coherent telecommunications, remote sensing, medicine, etc. Such lasers are generally realized by intracavity or external cavity frequency doubling of cw laser-diode (LD)-pumped solid-state Q-switched Nd-doped...

This work describes a cryogenic, electro-optically -switched Yb:YAG laser that generates 114-W average TEM power with 47% optical-to-optical efficiency. Pulse repetition frequency is 5 kHz, pulse duration is 16 ns full-width at half-maximum, and is less than 1.05.
