Electron density and temperature measurements in a laser produced carbon plasma

Plasma generated by fundamental radiation from a Nd:YAG laser focused onto a graphite target is studied spectroscopically. Measured line profiles of several ionic species were used to infer electron temperature and density at several sections located in front of the target surface. Line intensities of successive ionization states of carbon were used for electron temperature calculations. Stark ...

Wavefront-sensor-based electron density measurements for laser-plasma accelerators.

Characterization of the electron density in laser produced plasmas is presented using direct wavefront analysis of a probe laser beam. The performance of a laser-driven plasma-wakefield accelerator depends on the plasma wavelength and hence on the electron density. Density measurements using a conventional folded-wave interferometer and using a commercial wavefront sensor are compared for diffe...

Laser plasma density measurements using interferometry

Fabrication of an interferometer is planned at the UCSD Laser Plasma and Laser-Matter Interactions Laboratory. The primary goal of this project is to measure the density at early times in the evolution of highly transient laser created plasmas. We describe the design concepts and details of different kinds of interferometer for measuring density evolution, especially during early time of plasma...

Electron Density Determination in an Are Plasma by Laser Interferometry

In collison dominated plasmas the electron density is the most important parameter. Therefore laser interferometry is very attractive because it allows a direct determination of this quantity without any rigid assumptions such as, e.g., local thermodynamical equilibrium (LTE). For references see, e.g., Griem \ Alpher and White 2 or Kunze 3. In the experiment described in this paper we intended ...

Characterization of Expanding Laser Plasma Produced by Laser Ablation

This work is devoted to characterizing the plasma produced by nanosecond laser ablation. The expanding plasma was generated by the interaction of a home made XeCl excimer laser with a Cu target. The time-of-flight method was utilized as diagnostic tool of the plasma charged particles. By this method, in fact, we were able to measure the ion and electron currents, the charge-states and the energ...
