Time-resolved optical emission spectroscopic measurements of He plasma induced by a high-power CO2 pulsed laser

Time- and space-resolved spectroscopic characterization of laser-induced swine muscle tissue plasma

“…1. Pulses from a TEA CO 2 laser (Lumonics K-103) emitting at 10.591 μm are used for producing plasmas on a skeletal muscle sample of a swine [51]. To ensure sample homogeneity, swine tissues were lyophilized and compressed into a pellet.…”

“…The excitation wavelength was checked with a spectrum analyzer (Optical Eng. Co. [51,52]. The primary laser beam (divergence of 3 mrad) was angularly defined and attenuated by an iris of 17.5 mm diameter before entering into the vacuum chamber.…”

Time-resolved spectroscopic diagnostic of laser-induced plasma on germanium targets

“…1) and equipment used have been described elsewhere. 15 The experiments were carried out with a transversely excited atmospheric (TEA) CO 2 pulsed-laser with a pulse intensity of 0.27-4.9 GW cm À2 at a wavelength of 10.591 lm. The laser-pulse intensity was varied with the aid of several calibrated CaF 2 attenuating plates.…”

Measurement of electron number density and temperature of laser-induced Silver plasma

“…The Pulsed laser-induced plasmas (LIPs) has a intensive application in material processing, thin film deposition, environmental monitoring, biomedical studies, military safety usage, art restoration/conservation and metal analysis, which is being produced after laser irradiance on the surface of metals and is of a great interest since last few decades [1][2][3][4][5][6][7][8][9][10][11]. In LIPS method, a micro-plasma is produced in nanosecond when highly intense laser pulse interacts with a target material; resultantly vaporization take place and thus plasma produced expand along the path of distribution in the form of vapor plume.…”
