Morphology of Femtosecond Laser Ablated Borosilicate Glass Surfaces
We studied the morphology of borosilicate glass surface machined by femtosecond laser pulses. Our observations show that a thin rim is formed around ablated craters after a single laser pulse. When multiple laser pulses are overlapped, the crater rims also overlap and produce a surface roughness. The rim appears to be a resolidified splash from a molten layer generated during the ablation proce...
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 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 کاملToward nano- and microprocessing in glass with femtosecond laser pulses
In this paper, we report on the refractive index changes and vacancies that are induced in silica glass by the irradiation of ultrashort laser pulses. We fabricated waveguides, couplers, and gratings by the filamentation of femtosecond laser pulses. We demonstrate the formation and the movement of sub-micrometer or nanometer vacancies, called voids. We show the formation of three-dimensional sh...
