Title: Antanas Urbas: Innovator in Laser Processing Technology
Introduction
Antanas Urbas is a notable inventor based in Vilnius, Lithuania. He has made significant contributions to the field of laser processing, particularly in the fabrication of transparent materials. His innovative approach utilizes ultra-short laser pulses to achieve precise results in material processing.
Latest Patents
Antanas Urbas holds a patent for a "Method and device for laser processing of transparent materials." This invention focuses on the fabrication of materials that are mostly transparent to laser wavelengths. The method involves forming a non-centrosymmetric, non-diffracting beam using an optical element with at least two zones of birefringent structures. These structures change the Pancharatnam-Berry Phase according to specific rules for each zone. The energy distribution, phase, and polarization are influenced by the parameters of the incoming light. The pulse energy is carefully selected to utilize the main maximum of the distribution to create voids elongated in the desired direction. Additionally, side maxima lead to chemical changes between damages from adjacent pulses. The resulting void damages and chemical change zones create a precise cut line. The workpiece is then placed in a chemically aggressive solution, allowing the affected zones to dissolve faster than the unaffected ones, achieving cuts with an aspect ratio of up to 1/50.
