Time Resolved Laser-Induced Breakdown Spectroscopy of Human Hair

Experimental studies of the spectral-temporal characteristics of plasma generated on the surface of human hair by femtosecond laser pulses (40 and 650 fs) with a value of 1.1 mJ have been carried out. The time dependence of the intensity of Ca I (422.6 nm), Ca II (393.37 nm), Na I (588.98 nm), Mg I...

Zusammenfassung:	Experimental studies of the spectral-temporal characteristics of plasma generated on the surface of human hair by femtosecond laser pulses (40 and 650 fs) with a value of 1.1 mJ have been carried out. The time dependence of the intensity of Ca I (422.6 nm), Ca II (393.37 nm), Na I (588.98 nm), Mg I (285.21 nm), Mg II (280.2 nm), Zn I (213.8 nm), Zn II (202.5 nm) and the decay of the continuous plasma spectrum in the interval from 0 to 1 μs has been studied.
