Vanadium dioxide shows a passive and reversible change from a monoclinic insulator phase to a metallic tetragonal rutile structure when the sample temperature is close to and over 68°C. As a kind of functional material, VO2 thin films... more
www.hplsa2018.com On behalf of the Organizing Committee, we extend a warm and cordial welcome to you to be part of 22th Symposium on High Power Laser Systems and Applications, held conjointly with eminent researchers and scholars from... more
To assess the potential of a short pulsed laser to cut a posterior graft and bed for posterior lamellar keratoplasty (PLAK). Experimental study. Using the laser FEMTEC (20/10 Perfect Vision, Heidelberg, Germany), posterior lamellar... more
The ablation rates, as a function of the laser fluence, of the optically transparent polymers, Nylon-6,6 and PMMA, are reported using picosecond and subpicosecond laser pulses, obtained from a Regenerative Amplified Nd:YAG laser system.... more
High harmonic generation (HHG) of intense infrared laser radiation (Ferray et al., J. Phys. B: At. Mol. Opt. Phys. 21:L31, 1988; McPherson et al., J. Opt. Soc. Am. B 4:595, 1987) enables coherent vacuum-UV (VUV) to soft-X-ray sources. In... more
معادلات علي يوسف تم اكتشافها منذ 2016 بعدما قرأت كتب عن الثيرمودايناميك والكيمياء الفيزيائية، ولاحظت ان تناول هذه الكتب في عنوان الكيمياء الضوئية ليس مكتمل وانما هنالك ابواب ناقصة فمثلا لماذا يتفاعل الضوء مع هذه المادة دون غيرها، والظواهر... more
To assess visual and refractive outcomes of femtosecond laser for residual refractive error correction after refractive lens exchange (RLE) with multifocal intraocular lens (IOL) implantation.Prospective, nonrandomized, masked... more
In this study, we investigate the effects of CO2 laser polishing on microscopic structures fabricated by femtosecond laser assisted carving (FLAC). FLAC is the peripheral laser irradiation of 2.5D structures suitable for low repetition... more
The in situ synthesis and patterning of CdS nanocrystals in a polymer matrix is performed via multi-photon absorption. Quantum-sized CdS nanocrystals are obtained by irradiating a cadmium thiolate precursor dispersed in a transparent... more
