Micromachining Characteristics of Sapphire with Fifth HG Nd:YAG Laser
Autor: Kazuo Nakamura, Nobuo Yasunaga, Toshiyuki Noji, Hideyuki Horisawa
Publikováno v: Key Engineering Materials. 329:589-594
In order to reduce the thermal influences in laser machining of sapphire surface, effects of a short-pulse ultra-violet laser were investigated. For the UV laser, the Fifth harmonic generation (Fifth HG) wave of an Nd:YAG laser (wavelength:213nm) was

Machining Mechanisms of Si Wafers in Mechanochemical Polishing by Soft Abrasives
Autor: Nobuo Yasunaga
Publikováno v: Key Engineering Materials. :385-388
The mechanism of the mechanochemical polishing of Si wafers with BaCO3, CaCO3 and ZnO abrasives was investigated by polishing experiments carried out in air, O2 and Ar gas environments on dry condition and static heat treatment experiments of mixed p

Surface machining characteristics of sapphire with fifth harmonic YAG laser pulses
Autor: Hajime Emura, Nobuo Yasunaga, Hideyuki Horisawa
Publikováno v: Vacuum. 73:661-666
In order to reduce the thermal influences in laser machining of sapphire surface such as reattachment of molten material, cracks, etc., effects of a short-pulse ultraviolet laser were investigated. For the ultraviolet laser, the Fifth harmonic genera

Ultraprecision Machining. High Performance Polishing Method. Mechanochemical Polishing by Soft Abrasives
Autor: Nobuo Yasunaga
Publikováno v: Hyomen Kagaku. 22:187-196
The principle of mechanochemical polishing and examples of the method are described. By using the method we can polish hard and functional materials with the abrasive powders that are mechanically softer than the materials. If the powders supplied ar

Effects of a quartz beam-guide on high-precision laser-assisted etching of Al2O3 ceramics
Autor: Nobuo Yasunaga, H. Ashizawa, Hideyuki Horisawa, Noritoshi Akimoto
Publikováno v: Surface and Coatings Technology. 112:389-393
Laser-assisted chemical etching of ceramic materials has been attracting continuous attention as a laser microfabrication technique with relatively low power levels. In this study, in order to improve the accuracy of etching depth and diameter, the a
