Research ArticleOpen accessIn the keywordsComparison of 10 cm and 50 cm Long Iodine Cells in Iodine-Stabilized Diode Laser-Pumped Nd:YAG Laser at 532 nmPrayut Potirak, Monludee Ranusawud, Pichet Limsuwan, Prathan BuranasiriAn iodine-stabilized diode laser-pumped Nd:YAG laser system at 532 nm was developed at the National Institute of Metrology of Thailand (NIMT) for the first time in Thailand. Two iodine cells with the lengths of 10 and 50 cm were used for the comparison of frequency stability of Nd:YAG laser. The experiment was set for phase modulation spectroscopy. The Nd:YAG laser … …American Journal of Applied Sciences, Vol. 15, Issue 5 · 26 May 2018 · 7,891 accessesView PDFCite
Research ArticleOpen accessIn the keywordsControl of Bubble Formation at the Optical Fiber Tip by Analyzing Ultrasound Acoustic WavesViacheslav Viacheslavovich Kazakov, Vladimir Isaakovich Yusupov, Viktor Nikolaevich Bagratashvili et al.The problems of controlling the processes of generation of acoustic waves and microbubbles at the optical fiber tip of moderate-power surgical lasers with wavelengths of 1.9 µm and 0.97 µm using active and passive acoustic methods are considered. It is shown that microbubbles of various sizes can be detected with an ultrasound method, in which the interaction area is recorded … …American Journal of Engineering and Applied Sciences, Vol. 9, Issue 4 · 2 Nov 2016 · 8,490 accessesView PDFCite
Research ArticleOpen accessIn the keywordsNanoscale Pitch Standards Sample Fabricated using Laser-Focused Atomic DepositionYan Ma, Tongbao Li, Yajun Zhao et al.Problem statement: Nanotechnology is already a large sector of industry and science research and it is expected to continue to grow at very fast rate. The determination of absolute measurements of length at the nanometer scale and below is very difficult and expensive. So the nanoscale metrology standard is needed. Approach: The laser-focused atomic deposition is a new way to … …Current Research in Nanotechnology, Vol. 2, Issue 2 · 3 Sep 2012 · 7,249 accessesView PDFCite
Research ArticleOpen accessIn the keywordsAbout the Light DimensionsFlorian Ion T. Petrescu, John Kaiser CalautitLight is one of the most fascinating something of all the time. This paper aims to develop a tool with which one can determine with great accuracy the dimensions of light. Basically was entered a new relationship through which one may determine the size of a photon depending on the wavelength of light. Instead wavelength of light can be used … …American Journal of Applied Sciences, Vol. 13, Issue 3 · 28 Mar 2016 · 10,620 accessesView PDFCite
Research ArticleOpen accessIn the abstractShift of Zeeman Components of Ionic Spectral Lines Caused by the Angular Doppler EffectEugene OksThe angular Doppler effect was introduced by Garetz. While the usual Doppler effect is caused by the translational motion of the emitter, the angular Doppler effect is caused by the rotational motion of the emitter. It results into the frequency shift of a circularly-polarized light. In the present paper we analyze the angular Doppler effect caused by the rotational motion … …Physics International, Vol. 15, Issue 1 · 16 Jun 2025 · 6,460 accessesView PDFCite
Research ArticleOpen accessIn the abstractAdvantage of Classical Approximate Analytical Methods for Studying Rydberg States Over the Quantum CounterpartsEugene OksIn studies of atomic and molecular systems, approximate analytical methods play a significant role. This is because they can be used for benchmarking the results of numerical methods. Besides they offer a physical insight into the phenomena under consideration an insight impossible to achieve by numerical methods. Many approximate analytical methods were developed in such a way that each method … …Physics International, Vol. 14, Issue 1 · 2 Jul 2024 · 8,014 accessesView PDFCite
Research ArticleOpen accessIn the abstractModern Propulsions for the Aerospace IndustryRelly Victoria Virgil Petrescu, Raffaella Aversa, Antonio Apicella, Florian Ion Tiberiu PetrescuThis paper aims to contribute to the study of propulsion systems for modern aerospace vehicles with the obvious aim of improving them and to give them the ability to move much faster and easier in any direction, for a very long time, going through huge distances without the need of fuel refueling, as is the case with conventional, chemical propulsion. … …American Journal of Engineering and Applied Sciences, Vol. 11, Issue 2 · 12 May 2018 · 8,003 accessesView PDFCite
Research ArticleOpen accessIn the abstractPhysical Therapy Improved Hand Function in a Patient with Traumatic Peripheral Lesion: A Case StudyMarco Orsini, Julio Guilherme Silva, Clynton Lourenco Correa et al.Problem statement: Nerves are frequently injured by traumatic lesions, such as crushing, compression (entrapment), stretching, partial and total extraction, resulting in damages to the transmission of nerve impulses and to the reduction or loss of sensitivity, to the motility and to the reflexes of the innervated area.
