The effect of the crystallization and activated annealing of Si films using an excimer laser and the new CW blue laser are described and compared with furnace annealing for application in advanced TFTs and for future applications. Pulsed excimer laser annealing (ELA) is currently being used extensively as a low-temperature poly-silicon (LTPS) process on glass substrates as its efficiency is hig...

introduction: the role of laser in conservative management of oral disease is well established. laser procedures are common in the fields of oral surgery, implant dentistry, endodontic, and periodontic therapy. case: this case series describes the use of diode laser for the excision of oral exophytic lesions. all the patients attended the oral medicine department of shahid beheshti university o...

introduction: pyogenic granuloma (pg) is one of the inflammatory hyperplasia seen in the oral cavity. it is a reactional response to minor trauma or chronic irritation. the most common treatment of pg is surgical excision but alternative approaches such as laser excision have also been proposed especially for pediatric patients. case report: herein, we present a case of gingival pyogenic granul...

An experiment to investigate the influence of synthetic dye contrast agent in photoacoustic imaging biological tissue was conducted this study. This study uses a simple phocoacoustic system consists three main components, i.e., diode laser, condenser microphone, and custom-build X-Y stage. Characterization performed on components obtain appropriate settings The results optimal frequency duty cy...

the main goal in endodontic treatment is to eradicate or at least reduce intraradicular microbial population to levels that are more compatible with periapical lesions healing process. since endodontic infections are polymicrobial in nature, intraradicular survival of endodontic microbiota and their pathogenic properties are influenced by a combination of their virulence factors. the purpose of...

Copper is a useful material to show the high electric conductivity, heat conductivity and, antibacterial and virus inactivating effects. A blue diode laser with wavelength of 450 nm one suitable lasers for copper processing. High intensity precision materials processing technology using were developed. power 200 W was applied selective melting additive manufacturing. coating on stainless steel ...

Introduction: The aim of the present study was to determine burn intensity in retinal laser photocoagulation based on laser parameters; wavelength, power, beam size and pulse duration, using Optical Coherence Tomography (OCT), fundus camera, physical eye model and computer simulation in a clinical study.Materials and Methods: Participants were 10 adult patients between 50-80 years with prolifer...

Vascular lesions rise from abnormalities in blood vessels or endothelial proliferation. Capillary hemangiomas are formed by small capillaries surrounded by a layer of endothelial cells in a connective tissue stroma. Various treatments are used for these conditions like excisional surgery, sclerotherapy, and recently laser irradiation. In this case study, we report successful treatment of intrao...

Diode and DPSS lasers emitting a variety of wavelengths are now commonly incorporated into flow cytometers, greatly increasing our capacity to excite a wide variety of fluorochromes. Until recently, however, virtually no practical technology existed for generating yellow or orange laser light for flow cytometry that was compatible with smaller instrumentation. In this study, we evaluate several...
