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 ...

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 ...
Direct reconstruction of two ultrashort pulses based on non-interferometric frequency-resolved optical gating
(OSA - The Optical Society, 2021)
© 2021 Optical Society of America.We describe a non-interferometric ultrashort-pulse measurement technique based on frequency-resolved optical gating (FROG) with which pulses can be reconstructed directly, i.e. non-iteratively. ...
Hyper-Rayleigh scattering with picosecond pulse trains
(OPTICAL SOC AMER, 2008)
We propose a method for measuring hyper-Rayleigh scattering employing pulse trains produced by a Q-switched and mode-locked Nd:YAG laser. The use of the entire pulse train under the Q-switch envelope avoids the need of any ...
