Fabrication 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...
متن کاملFemtosecond 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 کاملFabrication of fully integrated antiresonant reflecting optical waveguides using the femtosecond laser direct-write technique.
Utilizing a recently developed two-step fabrication process, we have experimentally demonstrated what is to the best of our knowledge the first ever integrated antiresonant reflecting optical waveguide (ARROW), directly inscribed into bulk optical glass. The waveguide consists of an array of high-index contrast rods that surround an unmodified core. The transmission spectrum reveals the formati...
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...
