Femtosecond Laser Ablation of Sapphire
INSTRUCTION Sapphire is widely used in the field of optical components and micromechanical devices owing to its useful mechanical, optical, and electrical properties. However, sapphire is mechanically and chemically difficult to machine because of its high hardness and chemical stability. The difficulty of machining sapphire has restricted the development of advanced device structures. As sapph...
متن کاملStudy 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 کاملChemical analysis of human teeth.
THE dental literature contains numerous articles concerning the chemical analysis of human teeth.1-9 Most of this work was done in the early 1930's. Naturally, in these analyses the common chemical methods and procedures known at the time were used. Recently, a request was received for an analysis of some Greek teeth to compare their chemical compositions with that of domestic teeth. In recent ...
متن کاملFemtosecond laser near field ablation
The hi gh fi eld strength of fe mtosecond laser pulses leads to non I incar effects during the interacti on with condensed matter. One such e ffect is the ab latio n process, which can be initiated he low the threshold of common thermal ahlation if the excitation pul ses are suffic iently short . This effec t leads to structure formation, which is an isotropic because of the polari zation prope...
متن کاملFabrication of pillared PLGA microvessel scaffold using femtosecond laser ablation
One of the persistent challenges confronting tissue engineering is the lack of intrinsic microvessels for the transportation of nutrients and metabolites. An artificial microvascular system could be a feasible solution to this problem. In this study, the femtosecond laser ablation technique was implemented for the fabrication of pillared microvessel scaffolds of polylactic-co-glycolic acid (PLG...
