A laser machining device includes a laser light source, a spatial light modulator which includes a display unit, an objective lens, an image-transfer optical system, a camera and a controller. The controller executes first display processing and second display processing. According to first display processing, when the camera captures the image, the display unit displays a first phase pattern for adjusting a condensing position of laser light condensed by the objective lens to a first condensing position. According to second display processing, when the camera captures the image, the display unit displays a second phase pattern for adjusting the condensing position of the laser light condensed by the objective lens to a second condensing position different from the first condensing position in an irradiation direction of the laser light.

Additive manufacturing can include use of a laser-machining technique. Laser machining can be used to form cavities, trenches, or other features in an additively-manufactured structure. Spectroscopy can be performed to monitor a laser machining operation. For example, a laser-enhanced additive manufacturing process flow can include depositing a conductive layer on a surface of a dielectric layer, and conductively isolating a first region from a second region of the conductive layer using ablative optical energy, including applying ablative optical energy to the conductive layer, monitoring a spectrum of an ablative plume generated by applying the ablative optical energy, and controlling the ablative optical energy in response to a characteristic of the spectrum of the ablative plume.

The present invention relates to a hybrid material processing method includes steps of: emitting a laser beam toward an intended-to-be-modified area intended on a workpiece by a laser to perform a property modification for the intended-to-be-modified area; applying an optical image positioning assisted equipment to perform a precise positioning for a modified area or a positioning marker on the workpiece, so as to align a machine tool to the modified area; and driving the machine tool to perform a processing for the modified area.

The present invention relates to a composite container comprising a bottom film layer and a top film layer at least partially adhered to the bottom film layer. The top film layer is scored to form at least one resealable flap and at least one pull tab which is not adhered to the bottom film layer. The bottom film layer comprises at least one cavity opening. A cardboard layer is adhered on its lower surface to the upper surface of the top film layer, wherein the cardboard layer has at least one cavity opening which is substantially aligned with the scoring of the top film layer resealable flap and the cardboard layer is perforated to define a perimeter of at least one pull tab which is substantially aligned with and adhered, on its underside, to the upper surface of the top film layer pull tab.
