A method of machining includes removing material from a target region of a ceramic component to form a blind opening in the ceramic component via removing a bulk of the material by a laser machining operation and then removing a remainder of the material by a mechanical machining operation.

Methods and systems of using a laser beam to weld an object with a non-flat surface, including curved surfaces, are described, where at least one piece of the object is transparent. An optical guide with a flat surface and an interface surface is placed on a piece of an object to welded. The interface surface is fabricated to form-fit the non-flat surface of the object to be welded, and is opposite the flat surface. A liquid optical medium is applied between the non-flat surface and the interface surface, filling any gaps or surface defects. The laser beam is then transmitted through the optical guide, liquid optical medium, and into the object to be welded, to a location to be welded. The laser beam then welds the object to be welded at pre-determined points.

The present invention provides a machining fluid comprising a first phase fluid and a second phase fluid pressurized to be dissolved in the first phase fluid. The present invention further provides a machining device comprising an injecting head having a nozzle and a flow channel communicating with the nozzle for guiding the machining fluid to the nozzle injecting the machining fluid to an object. Alternatively, the present invention further provides a machining device comprising a light source for generating a laser beam and an injecting head having a nozzle and a flow channel communicating with the nozzle. The flow channel guides a machining fluid having a first phase fluid and a second phase fluid such that the machining fluid is injected to an object by the nozzle. The injecting head also receives the laser beam and guides the laser beam to the object through the nozzle.
