Presented at ICALEO 2011
We investigated the effects of cutting flexible glass substrates approximately 100 µm thick, using a CO2 laser full-body cutting technique. The technique uses a CO2 laser heating and water-jet quenching process to generate a tensile stress, which propagated a full-body crack along the cutting line. We examined the effects of process parameter variations on the cutting speed and glass edge quality. These parameters included laser conditions, water-jet coo...$28.00

Authors:
Sami Hendow, Multiwave Photonics; San Jose CA USA
Presented at ICALEO 2011
Pulse shape control and multipulsing are emerging as alternative means of enhancing material removal rates and improving the quality of machining operation. Various examples of multipulsing and pulse shape control are presented using a MOPA fiber laser, together with experimental and modeling results for 10 to 200 ns pulses showing peak power and pulse duration affecting ablation depth and HAZ. The laser is configured to produce fast bursts of pulses at tens of MHz, with temporal envelope in the range of 10 to 200 ns. These bursts a...$28.00
