A system and method fritter rock inside a cellar around a wellhead using high energy electromagnetic beams. The system includes a high energy electromagnetic emitter, an emitter controller, and a control loop. The high energy electromagnetic emitter is configured to aim a high energy electromagnetic beam into a cellar at the Earth's surface surrounding a wellhead, and to generate the high energy electromagnetic beam to be incident on a rock in the cellar, wherein the high energy electromagnetic beam fritters the rock. The emitter controller is configured by software therein to control an operation and the direction of the high energy electromagnetic beam. The control loop is configured to maintain alignment of the high energy electromagnetic beam with the cellar throughout the frittering to ensure beam/cellar coincidence.

A laser processing system capable of reliably determining an abnormality in a jet during laser process. The laser processing system comprises a nozzle including an emission opening configured to emit a jet of an assist gas along an optical axis of a laser beam, the nozzle being configured to form a maximum point of velocity of the jet at a position away from the emission opening; a measuring instrument configured to measure any of the velocity of the jet and a sound generated by the jet impinging on a workpiece; and an abnormality determination section configured to determine whether or not output data of the measuring instrument is different from reference data.

An apparatus for laser processing of very wide non-woven fabric materials at high speeds. This invention enables a laser beam to sever, perforate and pattern a large piece of fabric materials planarly disposed at regular or irregular spatial intervals over the entire width while the fabric passes from one roller to another roller at high speeds by precisely managing focus and intensity of the beam at the focal point on the web. A control system managing the laser processing system enables rapid reconfiguration of perforation patterns. The fabric can be woven or nonwoven, homogeneous or nonhomogeneous material with uniform or nonuniform thickness. An optical sensor is provided to sense the laser processing as it is performed and provide feedback to a system controller to optimize laser processing performance in real time.

A method is proposed for producing a packaging, having a method step of microperforation of a flexible material as a packaging film, comprising: provision of the flexible material as a packaging film, transport of the flexible material over a transport section, provision of a laser in order to generate a perforation of the flexible material with its beam. For a packaging with improved gas exchange, a laser system with a wavelength in the range of from 150 nm to 1064 nm, preferably from 355 nm to 532 nm, is used for the laser, and the perforation with the laser is carried out during the movement of the flexible material of the packaging film during the transport.
