Microwave Beam Diagnostic of Laser-Induced Plasmas
… the use of micro-impulse radar to detect laser-induced plasmas. The MIR actively interrogates the plasma to produce a reflected microwave signal from the plasma, and the device also detects the acoustic signature of the plasma. The acoustic MIR signal is similar to the signal received by a …

Optical emission spectroscopy of laser induced plasmas containing carbon and transitional metals
The spectroscopic, SEM and Raman measurements on carbon nanotubes under the exact conditions of which OES analysis were made showed that at a pressure of 400 Torr and a flow rate of 200 sccm, the quality and quantity of single-walled carbon nanotubes was the highest.

Laser-induced plasmas in air for pulsed broadband cavity-enhanced absorption spectroscopy
A pulsed laser-induced plasma (LIP) was generated in ambient air inside a high-finesse near-concentric optical cavity. The broadband optical plasma emission was successfully sustained within the cavity and the light leaking from the cavity was used to measure broadband absorption spectra of gaseous …

Coherent and partially coherent CW laser beam propagation in lens-like media: a diffractive ray-theoretic approach
… of coherent and partially coherent cw Gaussian laser beams in lens-like media (e.g., selfoc fibers, laser induced plasmas, etc.). The main results presented here extend those reported recently in connection with vacuum propagation and deterministic propagation through media characterized by a …
