Material-structure-performance integrated laser-metal additive manufacturing

Science, 2021
Cross-scale coordination Laser-based additive manufacturing has the potential to revolutionize how components are designed. Gu et al. suggest moving away from a strategy that designs and builds components in a serial manner for a more wholistic method of

Orbital angular momentum of light and the transformation of Laguerre-Gaussian laser modes.

Physical Review A. Atomic, Molecular, and Optical Physics, 1992
Laser light with a Laguerre-Gaussian amplitude distribution is found to have a well-defined orbital angular momentum. An astigmatic optical system may be used to transform a high-order Laguerre-Gaussian mode into a high-order Hermite-Gaussian mode ...

Laser desorption ionization of proteins with molecular masses exceeding 10,000 daltons.

Analytical Chemistry, 1988
In the following, the first results on ultraviolet laser desorption (UVLD) of bioorganic compounds in the mass range above 10000 daltons are reported. Strong molecular ion signals were registered by use of an organic matrix with strong absorption at the ...

A laser ablation method for the synthesis of crystalline semiconductor nanowires

Science, 1998
A method combining laser ablation cluster formation and vapor-liquid-solid (VLS) growth was developed for the synthesis of semiconductor nanowires. In this process, laser ablation was used to prepare nanometer-diameter catalyst clusters that define the ...

The Soliton Laser

Optics News, 1984
The soliton laser1 is a novel mode-locked device employing a length of single mode fiber in its feedback loop. Its pulse width can be made to have any desired value, down to a small fraction of a picosecond, through choice of the fiber’s length. Operation is based on the ability of single mode fibers, in the region (λ> 1.3 µm) of negative group ...
