Abstract:

Terawatt TW lasers have become commonplace since the development of the chirped-pulse amplification method using Tisapphire and Ndglass laser rods. We have measured the minimum visible lesion MVL thresholds for porcine1 Yucatan minipig skin using TW laser pulses. Our system produced laser pulses at 810 nm and sub-50 femtoseconds. These 1-2 TW laser pulses created multiple self-focusing SF filaments during propagation and were directed on the flanks of mini-pigs under anesthesia. We measured the pulse energies necessary to determine the ED50 skin damage thresholds.
