Spatial and temporal mapping of Al and AlO during oxidation in pulsed laser ablation of LaAlO3
We present the first spatio-temporal mapping of two simultaneously present species in a plasma used for pulsed laser deposition. We apply laser induced fluorescence spectroscopy (LIF) to map ground state populations of Al and AlO in plasma plumes generated by ablation of LaAlO3 in an O2 or Ar atmosphere. Around a specific distance from the target, we observe Al vanish simultaneously with the tu...
متن کاملMeasurement and analysis of atomic hydrogen and diatomic molecular AlO, C2, CN, and TiO spectra following laser-induced optical breakdown.
In this work, we present time-resolved measurements of atomic and diatomic spectra following laser-induced optical breakdown. A typical LIBS arrangement is used. Here we operate a Nd:YAG laser at a frequency of 10 Hz at the fundamental wavelength of 1,064 nm. The 14 nsec pulses with anenergy of 190 mJ/pulse are focused to a 50 µm spot size to generate a plasma from optical breakdown or laser ab...
متن کاملSpatial and Temporal Temperature Distributions in Municipal Solid Waste Landfills
Long-term spatial and temporal variations in temperatures have been investigated in covers, wastes, and liners at four municipal solid waste landfills located in different climatic regions: Alaska, British Columbia, Michigan, and New Mexico. Temperatures were measured in wastes with a broad range of ages from newly placed to old �up to 40 years�. The characteristic shape of waste temperature ve...
متن کاملOptical Opacity of Laser Induced Plasma in Distilled Water with NaCl and TiO2 Nanoparticles Impurities
In this paper, the dynamic behavior of laser induced optical breakdown in impure water was studied by using a pump- probe technique. The plasma was induced by a 1064 nm Nd:YAG laser pulse (with pulse duration ~10 ns) in distilled water with two types of impurities: (I) a solution (highly diluted salt water as a conductor) and (II) a colloidal (TiO2 in colloidal nanoparticle form as a dielectric...
متن کاملTemperature distributions of solid particles in a plasma stream
2014 An original method for the statistical analysis of the temperature of solid particles in a plasma stream is presented. The apparatus and calibration method are described. Temperature distributions of Al2O3 particles sprayed in an argon-hydrogen plasma were investigated. REVUE DE PHYSIQUE APPLIQUÉE TOME 12, SEPTEMBRE 1977, Classification Physics Abstracts 52.70
