Laser machining system for a component and laser machining process

Abstract

A system (1) for laser machining, specifically cutting, a component, includes a source (L) for emitting a pulsed laser beam, a first subsystem (LDO) for adjusting the polarization of the laser beam, at least a first and a second deflector (EOD), having non-parallel axes, a second subsystem (LOO) for adjusting the polarization of the beam exiting the deflectors, a deflector control subsystem (GRP), a synchronization subsystem (DG) for synchronizing the laser beam emission source with the control subsystem (GRP), a first focusing subsystem (F) comprising a first lens (FT) and positioned after the second subsystem for adjusting the polarization of the beam exiting the deflectors, a subsystem for simultaneously controlling the divergence and deflection of the laser beam at the output of the deflectors, as well as a second focusing subsystem (RF) and a propagation module (SPF), the sub-system for simultaneous control of divergence and deflection being positioned between the output of the deflectors and the first focusing sub-system (FT). A beam stabilization subsystem (MS) is positioned downstream of the laser source and/or upstream of a first deflector (AOD), the system being configured to create a precession of the laser beam.
