Spatially and temporally resolved temperature measurements of plasma generated in percussion drilling with a diode-pumped Nd:YAG laser

Spatially and temporally resolved temperature measurements of plasma generated in percussion drilling with a diode-pumped Nd:YAG laser

Results of spectroscopic temperature measurements of the laser-induced plasma generated during percussion drilling with a high power diode-pumped, pulsed Nd:YAG laser are presented. SAE 52100 steel was drilled with varying average powers. Helium and oxygen were each used as the shield gas. Emission spectra were collected with a monochrometer and an intensified charge coupled detector connected ...

Spatially and temporally resolved optical measurements in micro discharges

Optical measurements provide a convenient way to determine plasma properties such as particle densities and temperatures. Since optical measurements are usually conducted externally, they give only little information about the spatial distribution of the plasma. This is especially egregious when dealing with micro discharges. Firstly, micro discharges usually show a spatial non-uniformity, and ...

Spatially resolved temperature measurements in a flame using laser-excited two-line atomic fluorescence and diode-array detection.

Spatially resolved temperature measurements in a CH(4)-air flame have been achieved using two-line laser-induced fluorescence from indium atoms seeded to the flame.

Temporally and Spatially Resolved Plasma Spectroscopy in Pulsed Laser Deposition of Ultra-Thin Boron Nitride Films

Diode-pumped Yb:GSO femtosecond laser.

Compact femtosecond laser operation of Yb:Gd(2)SiO(5) (Yb:GSO) crystal was demonstrated under high-brightness diode-end-pumping. A semiconductor saturable absorption mirror was used to start passive mode-locking. Stable mode-locking could be realized near the emission bands around 1031, 1048, and 1088 nm, respectively. The mode-locked Yb:GSO laser could be tuned from one stable mode-locking ban...
