FIG. 1.

(Color online) Experimental setup. Side imaging and LIDAR detection of a filament-induced lead plasma.

Image of FIG. 2.
FIG. 2.

Spectra of filament-induced lead plasma with delay times of (a) and (b) , respectively.

FIG. 3.

Partial energy diagram of Pb I and corresponding transition wavelengths.

Image of FIG. 4.
FIG. 4.

Spectrum of the filament-induced lead plasma with a delay time of (dotted) and multipeak Lorentzian fitting (solid lines). The Stark broadening profile of Pb I at was used for the determination of the electron density.

Image of FIG. 5.
FIG. 5.

Electron densities of the lead plasma as a function of delay time.

Image of FIG. 6.
FIG. 6.

(a) Typical Boltzmann plot obtained with a delay time of and (b) plasma temperature as a function of delay time.

Image of FIG. 7.
FIG. 7.

Spectra recorded with a LIDAR configuration. The sample is located at (a) , (b) , (c) , and (d) away from the focal lens. For all cases, the gate widths are and the delay times are (with regard to the laser arriving time on the target).

Image of FIG. 8.
FIG. 8.

Single-shot spectrum of the lead plasma obtained with a delay time, gate width, grating, and a gain of 200.

Image of FIG. 9.
FIG. 9.

Extrapolation of the single-shot detection limit.
