Application of pulsed laser ND: YAG in superduplex steel uns S 32750: Autogenous laser welding, laser welding with refusion process by laser and hybrid welding (laser/Gtaw)
(2020-01-01)
The families of duplex and superduplex steels were developed to serve sectors that demand steels with extreme mechanical capacity and good corrosion resistance. Such characteristics are due to their structure being composed ...
Multifractality and the effect of turbulence on the chaotic dynamics of a He-Ne laser
(Spie, 2013-09)
We propose the use of multifractal detrended fluctuation analysis (MF-DFA) to measure the influence of atmospheric turbulence on the chaotic dynamics of a HeNe laser. Fit ranges for MF-DFA are obtained with goodness of ...
The vinyl bromide optically pumped far infrared laser: New large offset emissions
(Institute of Electrical and Electronics Engineers (IEEE), 2001-04-01)
We present the results of a study on vinyl bromide for the search for new far infrared (FIR) laser lines. As the pump source, we use a CW waveguide CO2 laser with a tunability of 290 MHz around each line in order to pump ...

Construction and characterization of a CO2 wave guide laser with a special electrode design for materials processing
(2001-01-01)
We describe the design and construction of an efficient tunable CO2 wave guide laser which was used for thermal graving of predigitalized images over polymeric materials. The small internal diameter of the cylindrical wave ...
Improvements on a laser scattering technique for droplet size measurements applied to a gas-liquid separation equipment
(Elsevier, 2011-02)
The knowledge of droplet size distributions in a gas-liquid separation equipment is of high relevance due to the importance of removal efficiency in these systems. Different techniques could be used to measure droplet size, ...
