Machining property of Cobalt doped glass by using Nd:YAG(532nm) laser |
| 초록 |
Suitable glasses for laser micromaching using a Nd:YAG laser have been developed. The composition of glasses is (70-x)SiO2-xB2O3-10Na2O-10CaO (x=0, 10, 15, 20, 25, 30). These glasses contain the Co ions in glass matrix (adding to the mother glass). After machining with the 2nd harmonic beams of a pulsed Nd:YAG laser, the bump in the glass host, the pit at the bump in the glass host and the sole pit were(was) formed. This report was conducted for researching as for relationship between bonding intensity of glass and thermo-mechanical properties, and for finding out the possibility of the fabrication of micro lens array (MLA). The maximum height of bump in the glass was 16μm and a diameter was 262.3μm. We found that the Co ions acted as sensitizers in laser machining of the glasses and this process can be used for MLA fabrication process. |
