Laser Sculpting and Processing of Silicon for Photovoltaics
Bek, Alpan (2017-12-07)
Direct writing of photonic and fluidic devices in Si by means of laser processing is of great importance as it promisses low-cost, rapid fabrication of Si devices. Although Si microfabrication techniques are well-established and technologically mature, the fabrication time and costs are still of importance as clean room environment, repetitive photomasking, mask aligning, thermal processing steps are typical requirements. Advancements in fiber laser technology has reached a stage such that high average powe...
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...

Laser-induced ignition of solid propellants for gas generators
Ulaş, Abdullah (Elsevier BV, 2008-05-01)
An experimental study was conducted to evaluate the ignitibility of a family of potential gas-generator solid propellants under different CO(2) laser heat fluxes and chamber operating conditions. Six types of solid propellant were tested: one baseline and five variations. The ingredients of the baseline propellant were ammonium nitrate, guanidine nitrate, potassium nitrate, and polyvinyl alcohol. The other five propellant variations were obtained by adding different amounts of carbon black, ammonium perchlo...
