High-Power Laser Systems In article number 2100741, Jiexi Zou and Xuechun Lin summarize the characteristics key technologies of solid-state lasers. cover design, three types classic high-power laser configurations have been integrated. A disk multi-slabs are distributed in tandem, beam lasing from further penetrates through slabs amplifies. Although fiber lasers an insufficient energy output ca...

optimization of process parameter is one of the ideal goals in laser sintering. the results of this process were measured as output parameters like: density, micro hardening, macro hardening, tension, roughness, stiffness, balling. in this paper, the influence of input parameter such as laser power, scan speed, material powder and etc are surveyed on output parameter like balling affection and ...

introduction: the aim of this study was to evaluate and compare microhybride composite treated by bur and different power of erbium, chromium doped yttrium scandium gallium garnet (er,cr:ysgg) laser by scanning electron microscope (sem). methods: 21 microhybride composite blocks (diafil tm, diadent, korea) with 2 × 4 × 4 mm dimensions were made. the bonding surface of these blocks were polished...

aim and background:   knee osteoarthritis (oa) is a prevalent and disabling disease. periarticular corticosteroid injection has been traditionally used for the pain control in these patients. recently low power laser has been introduced as a therapeutic option. this study was conducted to evaluate the efficacy of low power laser added to periarticular steroid injection for long-term treatment o...
