METHOD AND APPARATUS FOR WORKING ROCK USING LASER |
| 摘要 |
<P>PROBLEM TO BE SOLVED: To provide a method which makes boring possible even when quartz glass or silicon dioxide is deposited as molten dross by laser beam irradiation. <P>SOLUTION: The laser beam irradiation position 12 of a workpiece 100 is irradiated with laser beams at least 1.2 μm in wavelength with a large absorption factor in a liquid, for example, CO<SB>2</SB>laser beams through the liquid 31 from a laser 20. By a high pressure generated in the bubbles of an advance flow 13 of fine bubbles produced in the liquid, the molten dross is scattered to apply working such as boring to a rock 100. <P>COPYRIGHT: (C)2008,JPO&INPIT |
