Ultrashort laser pulse retrieval using single-shot VAMPIRE
(IEEE, 2014)
Characterizing ultrashort laser pulses is a challenging task. By now several methods are established which can be divided into interferometric methods like SPIDER (spectral phase interferometry for direct electric field ...
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 ...
Effects of rotation in the laser-pulse photoassociation in a thermal gas of atoms
(Spie-int Soc Optical Engineering, 2013-01-01)
Photoassociation is a possible route for the formation of chemical bonds. In this process, the binding of colliding atoms can be induced by means of a laser field. Photoassociation has been studied in the ultracold regime ...
Pulsed Nd:YAG laser welding of UNS S 32205 duplex stainless steel
(2016-01-01)
This paper reports an experimental study of laser welding on duplex stainless steel UNS S32205 employed in the oil and natural gas industries. A pulsed Nd:YAG laser was used to weld the specimens. Bead on plate condition ...
Effects of laser beam energy on the pulsed Nd:YAG laser welding of thin sheet corrosion resistant materials
(Trans Tech Publications Ltd, 2014-01-01)
The aim of this study was to value the possibility to join, for pulsed Nd:YAG laser welding, thin foils lap joints for sealing components in corrosive environment. Experimental investigations were carried out using a pulsed ...
Effect of pulse repetition rate and number of pulses in the analysis of polypropylene and high density polyethylene by nanosecond infrared laser induced breakdown spectroscopy
(ELSEVIER SCIENCE BVAMSTERDAM, 2012-02-01)
Pulse repetition rates and the number of laser pulses are among the most important parameters that do affect the analysis of solid materials by laser induced breakdown spectroscopy, and the knowledge of their effects is ...
One-dimensional analytical model for oxide thin film growth on Ti metal layers during laser heating in air
(2001-05-15)
This paper presents the theoretical and experimental results for oxide thin film growth on titanium films previously deposited over glass substrate. Ti films of thickness 0.1 μm were heated by Nd:YAG laser pulses in air. ...
