Abstract
Conference Title: 2014 Conference on Lasers and Electro-Optics (CLEO) Conference Start Date: 2014, June 8 Conference End Date: 2014, June 13 Conference Location: San Jose, CA, USA We report on focus-optics free laser micro-processing of several materials using up to milli-joule energy-level fs-pulses directly delivered by 10m-long hypocycloid-core kagome HC-PCFs. The ablation rate and depth were studied showing high-precision drilling.
