This work presents a novel white light device. An yttrium aluminum garnet (YAG) phosphor-incorporated zinc oxide (ZnO) film is deposited on a slide glass substrate by ultrasonic spray pyrolysis. A nanoflower consisting of a hexagonal nanopetal is formed on the surfaces of the samples, and the sizes of the nanopetal are approximately 200 to 700 nm. Additionally, the nanopetal becomes blunted wit...

In the present work, four polymeric nanocomposite PNC coatings were prepared with different concentrations of yttrium aluminum garnet nanoparticles YAG-NPs in polyvinyl butyral PVB matrix. The corrosion protection of the PNC coatings applied on the carbon steel surface was investigated in 1.0 M HCl solution by electrochemical impedance spectroscopy EIS. The YAG-NPs were synthesized by pulse ele...

Background: To analyse the rate of complications associated with Nd YAG posterior capsulotomy. Methods: This prospective clinical study was conducted in Holy Family Hospital over a six-month period. It included five hundred and fifty patients in out door Eye Department, Holy Family Hospital treated with Nd YAG laser capsulotomy due to posterior capsular opacification after cataract surgery. The...

Passively Q-switched ceramic Nd3+:YAG lasers with ceramic Cr4+:YAG saturable absorbers are demonstrated. When the lasers are pumped by a 1-W cw laser diode, optical-optical efficiency as great as 22% is obtained with Cr4+:YAG of initial transmission ranging from 94% to 79%. The results are similar to those in their crystalline counterparts. The operation of Brewster's angle and the polarization...

Photodynamic therapy (PDT) utilizing Photofrin is proving to be effective for the treatment of early stage lung cancers. The effect of PDT utilizing YAG-OPO laser as new light source was evaluated in 26 patients (29 lesions) with early stage lung cancers. YAG-OPO laser is solid state tunable laser which is easy to change wavelength between 620 and 670 nm exciting various kinds of photosensitize...

There is an increasing demand for high-intensity subnanosecond lasers for emerging industrial applications. While femtosecond and picosecond laser sources are considered promising, they suffer from the significant drawbacks of increased complexity and cost. In this regard, we demonstrate a unique edge-pumped passively Q-switched Nd∶YAG∕Cr4þ∶YAG microchip laser. The microchip is made of a Nd∶YAG...

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...

Since 1980, advanced lung carcinomas were treated with palliative laser therapy for the purpose of opening the endobronchial stenosis and obstruction by either photodynamic therapy (PDT) or Nd-YAG laser treatment at Tokyo Medical University. A total of 258 lesions were treated, 81 by PDT and 177 by Nd-YAG laser treatment. PDT achieved effective results in 61 (75%) of 81 lesions. In the Nd-YAG l...

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...
