A deposition apparatus and a deposition method are described. The deposition apparatus includes an accommodating element, a plurality of lasers and a carrier. The accommodating element is configured to accommodate a material. The lasers are disposed at a periphery of the accommodating element, and are configured to simultaneously emit a plurality of laser beams toward the material to melt the material to form a deposition liquid. The carrier is disposed under the accommodating element and the lasers, and are configured to carry the deposition liquid.

A method of cutting thin flexible glass substrates utilizing a feedback loop configured to monitor a position of a crack tip relative to an irradiated zone on the glass substrate. A process controller including the feedback loop controls at least one of a laser beam power, a laser speed or a cooling fluid speed based on the distance between the crack tip and the irradiated zone.

A method of machining cooling holes includes providing a workpiece in which a cooling hole is to be formed. The cooling hole, once formed, defines distinct first and second sections. The workpiece is secured in a fixture that is mounted in a first machine. In the first machine, a laser is used to drill a through-hole in a wall of the workpiece. The through-hole is spatially common to the first and second sections of the cooling hole. After drilling the through-hole, the fixture with the workpiece secured therein is removed from the first machine and mounted in a second machine. In the second machine, ultrasonic machining is used to expand a portion of the through-hole to form the second section. An abrasive slurry used in the process is drained through the through-hole during the ultrasonic machining.
