DAMAGE THRESHOLD IN ABLATION REGIME INDUCED BY FEMTOSECOND LASER IRRADIATION ON TRANSPARENT MEDIA

The current work is a case study of ongoing in-depth extensive fundamen-tal research on the plasma formation and relaxation dynamics in transparent media induced by mid-and short-wavelength infrared laser pulses. The exper-imental investigation is performed on a 35 fs-laser system setup. The working parameters such as laser energy and the number of pulses are varied. The exper-imental measurements are applied on borosilicate glass samples doped with gold nanoparticles. The effects of the applied laser pulses and their consequence on laser-induced ablation damage thresholds are investigated and discussed. The results from this case study provide valuable information and a deeper under-standing plasma formation and dynamics induced by femtosecond infrared laser pulses in solid transparent glass media.
