Paper Abstract

As the laser technology advances and the availability of high power femtosecond pulsed laser systems increase, the urgency to have damage thresholds and ED50 data on these new laser systems becomes more and more prominent. In this study, we have used >50 mJ, 30-50 femtosecond laser pulses at ~810 nm that produced self-focusing filaments in the atmosphere. Then, these high-powered (1-3 terawatt) filaments were placed on a grid pattern on a piece of chamois. The effects and the damage caused by the filaments were investigated. The results were compared to the damage threshold data. Ultimately, our purpose is to extend this study to porcine skin and to measure Minimum Visible Lesion (MVL) thresholds and to determine the ED50 for exposures at above mentioned laser pulses.
