TLDR
In this paper, a laser via drilling system, and a method of use thereof, is provided, where the output beams from the independently controlled laser systems are combined using a beam splitter that combines the beams into single or multiple processing beams.Abstract:
A laser via drilling system, and a method of use thereof, is provided. The apparatus uses two or more laser systems to achieve processing parameter flexibility. The output beams from the independently controlled laser systems are combined using a beam splitter that combines the beams into single or multiple processing beams. The operational flexibility of the system can be further enhanced through the use of multiple EO modulators and a polarization sensitive beam splitter.read more
