Study of laser ablation using nano-second laser pulses
In this paper, the laser ablation process based on the irradiation of nanosecond pulsed lasers on a copper target surface in the presence of Helium gas is studied. The dynamical behaviors of the generated plasma in the helium gas and evaporated copper at the atmospheric pressure are examined using a laser pulse, laser wavelength of and intensity of 7×1010W/cm2. A one-dimensional thermal model ...
متن کاملاثر کندگی لیزری (laser ablation) توسط مکانیزم فتوترمال در پیلمرها
در طی این پایان نامه ما ابتدا ضمن بیان روند تاریخی علم پلیمرهای و فرایند ablation، مقدار راجع به کاربردهای ablation صحبت می کنیم. سپس در مورد پلیمرها و مشخصات و ویژگیهای مختلف مربوط به آنها مطالبی را ارائه می دهیم. در ادامه همراه با ارائه مدلهای گوناگون مربوط به فرایند ablation و تفاوت آنها با یکدیگر، "مدل فتوگرمایی مرتبه یکم" را به طور مفصل مورد بحث قرار می دهیم. در پایان برنامه های کامپیوتری ...
15 صفحه اولLaser Ablation Simulation Including Time Dependent Atomic Processes
An integrated Laser Ablation Fluid RAdiation simulation Code (LAFRAC) has been developed to estimate behaviors of highly energetic ions and neutral particles from laser produced plasmas, and to estimate ionization and recombination processes. Neutral particles cannot be controlled by electric and/or magnetic forces. Therefore, estimation of the number of neutral particles and mitigation of them...
متن کاملCT-guided laser probe for ablation of brain tumors
In this study, 22 patients (15-75 years old) were selected and transferred to CT scan for tumor ablation. For ablations, after prep and drep under the local anesthesia and mild sedation in proper position, small incision made and special needle inserted and guided by proper direction to the core of the tumor. Then, laser probe inserted through the needle and laser energy delivered. Although we ...
متن کاملMultiscale Modeling of Laser Ablation: Applications to Nanotechnology
Computational modeling has a potential of making an important contribution to the advancement of laser-driven methods in nanotechnology. In this paper we discuss two computational schemes developed for simulation of laser coupling to organic materials and metals and present a multiscale model for laser ablation and cluster deposition of nanostructured materials. In the multiscale model the init...
