A new application of glass surface treatment is presented here. Fine polishing of optical fiber end core/cladding surface, is performed. A small power monomode longitudinal 10 W cw CO2 laser is used. A decrease of the roughness from about 5 microns to hundreds of nanometres was achieved The microstructure of the surfaces has been studied using atomic force microscopy. Applications of polished fiber surfaces are given.

Laser polishing of optical fiber end surface
Udrea, M; Orun, H; Alacakir, A (2001-09-01)
A new application of glass surface treatment is presented. Fine polishing of optical fiber end (silica type), core/cladding surface is performed. A low-power monomode longitudinal 10-W continuous wave CO2 laser is used. Laser power density is 140 W/cm(2). The beam is spatially filtered to increase the beam uniformity. A decrease of the roughness from 2.5 mum average to less than 100 nm is achieved. The microstructure of the surfaces is studied using atomic force microscopy. An optimum irradiation time of ex...
Nano patterning of AISI 316L stainless steel with Nonlinear Laser Lithography: Sliding under dry and oil-lubricated conditions
Gnilitskyi, Iaroslav; Rotundo, Fabio; Martini, Carla; Pavlov, Ihor; Ilday, Serim; Vovk, Evgeny; Ilday, Fatih Omer; Orazi, Leonardo (2016-07-01)
Femtosecond laser-based Nonlinear Laser Lithography (NLL) was applied to AISI 316L stainless steel, which requires surface modification to achieve satisfactory tribological behaviour. NLL advances over the well-known Laser Induced Periodic Surface Structures (LIPSS) in terms of uniformity and long-range order of high speeds, over large areas. A galvanometric scanner head was used for an high production rate. Dry and lubricated sliding tests, considering different orientations of the nanotexture showed that ...
Monomode hybrid longitudinal CO2 laser for material processing
Udrea, M; Alacakir, A; Bilikmen, S; Kusdemir, O; Pervan, O (1999-10-27)
A hybrid with small average power CO2 laser is presented. The laser might operate both in a continuous regime and in a pulsed one. The advantages of the good optical quality beam of a longitudinal discharge laser and of a high power peak pulse are simultaneously achieved. A high voltage capacitor which is switched on by means of a rotary spark gap sustains the pulsed regime. The commutation between the two regimes might be easily done and a hybrid operation is also obtainable. Glass surface treatment using ...
Surface modification of unsized PAN- based carbon fiber by using high frequency single and dual RF discharge system
Erözbek Güngör, Ümmügül; Bilikmen, Kadri Sinan; Akbar, Demiral; Department of Physics (2014)
The aim of this thesis is to examine the effects of HF-RF nitrogen plasma treatment on unsized PAN-based carbon fiber surfaces. The fibers were treated under different plasma processing conditions; exposure times, RF powers and gas pressures in a homemade RF-PECVD reactor having two modes; single “40.68 MHz” and dual “40.68 /2.1 MHz”. Then, Raman and FT-IR spectroscopies were used to analyze the structure and functional groups of the fibers, respectively. Also, tensile strain of the samples was tested with ...
Slicing Crystalline Silicon Wafer by Deep Subsurface Laser Processing and Selective Chemical Etching

In this work, we demonstrate use of laser-induced silicon slicing (LASIS) technique to fabricate crystalline silicon (c-Si) slices [1]. In LASIS method, a nanosecond-pulsed fiber laser operating at 1.55 μm wavelength, focused deep in Si subsurface induces structural modifications near the focal point due to multiphoton absorption. The raster scan of the focal position inside of the sample, positioned in cross-sectional plane with respect to laser beam, produces a quasi-2D modified Si region. The modified Si...
