BACKGROUND Striae distensae or stretch marks are atrophic linear dermal scars with epidermal atrophy. There are many therapeutic options for management, but no consistently effective modality is available yet. OBJECTIVE We compared the efficacy of 1064 nm long pulse (LP) Nd: YAG laser and 2940 nm variable square pulse (VSP) erbium: YAG laser in the treatment of striae distensae. METHODS Twe...

Experiments were performed to find out plasma parameters for Nickel and Titanium metals which were irradiated in air (1 atm) to produce plasma plume using Q switched Nd: YAG pulsed laser of 1.1 MW, 10 m J, 1064 nm and 9-14 ns. Langmuir probe was used as a diagnostic tool. The signals at different probe voltages were recorded on digital storage oscilloscope. The information carried by the signal...

Tunable subpicosecond pulses are generated by synchronously pumping a dye laser with the pulse-compressed and frequency-doubled output of an acousto-optically mode-locked cw Nd:YAG laser. The pulses are amplified at a repetition rate of 1 kHz, using the frequency-doubled output of a cavity-dumped, acousto-optically mode-locked, Qswitched, cw pumped Nd:YAG laser. Amplified transform-limited puls...

Neodymium: Yttrium-Aluminum-Garnet (Nd-YAG) laser treatment of epithelial ingrowth was found promising with high success rates in cases of primary post-LASIK epithelial ingrowth. However, the application range of this procedure is not well-known. For the first time, the authors report the outcome of a patient treated with Nd-YAG laser for multiple recurrences of post-laser in situ keratomileusi...

OBJECTIVE To determine the frequency of raised intraocular pressure (IOP) after Nd: YAG laser posterior capsulotomy and its association with the energy used with raised versus normal intraocular pressure in pseudophakes. STUDY DESIGN Comparative, cross-sectional study. PLACE AND DURATION OF STUDY Ophthalmology Department, PNS Shifa Hospital, Karachi, from August 2008 to February 2009. MET...

Thresholds for retinal vitreal and contained hemorrhages were determined for 1064 nm laser light at 30-nsec and 4-nsec pulsewidths. Rhesus monkeys received graded exposures from a neodymium-yag laser onto either the macular or extramacular region of the retina. Contained hemorrhages appeared as concentric ring structures with white punctate centers. The vitreal hemorrhage was characterized by t...

Posterior capsular opacification, also known as after cataract develops in 33 % of patients after uneventful cataract surgery. Nd-YAG Laser capsulotomy is the treatment of choice for PCO and is routinely performed by the general ophthalmologist on an OPD basis. Endophthalmitis, although a rare complication after Nd-YAG Laser capsulotomy, has been reported in the literature. We report a case of ...

This work represents a novel method to determine phosphorus (P) concentration in phosphogypsum (PG) waste samples using calibration-free laser-induced breakdown spectroscopy (LIBS). A 50 mJ Q-switched Nd: YAG laser has generated the PG LIBS spectrum. Spectroscopic analysis of plasma evolution been characterized by electron density Ne and temperature Te emission intensity stark broadening for P ...
