摘要

"Methods of laser processing to execute the process of laser ablation on a workpiece and to manufacture an ink jet recording head, ink jet recording device, and,Ink jet recording head.A method of laser processing to execute the process of laser ablation on a workpiece by radiation of laser beam on the workpiece includes the step of forming.At the same time, a plurality of forms of processing arranged a predetermined interval, by the use of laser beam of several pulses,With the temporal and spatial energy density extremely high radial of a laser oscillator and the laser beam oscillating in time of radiation pulse of a picossegundo or less.With the method of laser processing thus structured is possible to execute processing is a highly accurate without creating a by-product.As well as to prevent thermal energy converted from essentially be accumulated on a work piece, such as resin.What causes the workpiece to be melted or thermally expanded during the operation of laser processing.
