Show Abstract
We report on a localized high-density electron beam in large-area microwave discharges in argon. The beam is observed only for certain antenna configurations at gas pressures of about 50 mTorr, and it strongly modifies the radial plasma density profiles. The beam current near the quartz plate is estimated to be ≈140 mA/cm2. © 2003 American Institute of Physics.

Show Abstract
While substantial progress has been achieved in understanding laser ablation on the nanosecond and picosecond time scales, it remains a considerable challenge to elucidate the underlying mechanisms during femtosecond laser material interactions. We present experimental observations of electronic excitation inside a wide band gap glass during single femtosecond laser pulse (100 fs, 800 nm) irradiation. Using a femtosecond time-resolved imaging technique, we measured the evolution of a laser-induced electronic plasma inside the glass and calculated the electron number density to be on the order of 1019 cm−3. © 2003 American Institute of Physics.

Show Abstract
The time-dependent density of mercury ions, sodium ions, and electrons is determined experimentally at the center of a high-pressure mercury discharge with sodium iodide as additive operated on alternating current within transparent quartz tube. The technique used is based on emission lines, and is independent of thermodynamic equilibrium assumptions. The results show that at sinusoidal low-frequency excitation the electrons come mainly from mercury ionization, the electron and mercury-ion densities vary strongly within the ac cycle, whereas the modulation of the sodium-ion density is significantly less pronounced. Results are also obtained assuming thermodynamic equilibrium and compared with the initial ones. © 2003 American Institute of Physics.
