Patent number: 7630147Abstract: Apparatus, systems, methods and devices of an optical system for producing a laser beam having pitchfork profile. The system includes a laser source providing an input Gaussian beam, refractive optical lenses for converting the input Gaussian beam into a super Gaussian beam. A focusing lens focuses the super Gaussian beam, where by diffraction effect after the focusing lens, the beam profile near a focal spot is a pitchfork shaped beam. In an embodiment, the refractive optical lenses are plano-aspheric lenses. The pitchfork shaped beam is produced by passing the input Gaussian beam through plano-aspheric lenses to produce the super Gaussian output beam, and passing the super Gaussian output beam through a focusing lens to produce the output beam having a pitchfork profile. In an embodiment, the pitchfork shaped beam is applied to laser microvias drilling in electronic packaging to produce residue free holes at reduced production cost with simplified procedures.Type: GrantFiled: February 16, 2007Date of Patent: December 8, 2009Assignee: University of Central Florida Research Foundation, Inc.Inventors: Aravinda Kar, Chong Zhang, Nathaniel R.
