In 2008 scientists at the Lawrence Livermore National Laboratory in California produced large quantities of antimatter by directing an extremely powerful laser at a tiny gold disc.
"but you need a powerful laser, and, even so, the material needs to be a many micrometers
Researchers from the University of Cambridge have used this relationship, in combination with powerful lasers and nanopatterned gold surfaces
The sensing mechanism, designed by Dr Ventsislav Valev and Professor Jeremy Baumberg from the Cavendish Laboratory, in collaboration with colleagues from the UK and abroad, uses a nanopatterned gold surface in combination with powerful lasers.
By using powerful lasers however, second harmonic generation (SHG) chiroptical effects emerge, which are typically three orders of magnitude stronger.
The method involves using a powerful laser to physically damage the optical equipment used to send
however it also requires significantly more powerful lasers than those needed for terahertz accelerators. The physicists underline that terahertz technology is of great interest both with regard to future linear accelerators for use in particle physics,
a novel wind lidar called Aladin incorporating two powerful lasers, a large telescope and very sensitive receivers.
When a powerful laser interacts chemical and biological molecules, the process can excite vibrational modes of these molecules and produce inelastic scattering, also called Raman scattering, of light.
While rich in details, the signal from scattering is weak and difficult to read without a very powerful laser.
With a precise and powerful laser that etches a pattern of micro -and nanoscale structures onto the surface of metal--building on earlier work that used laser-patterning to absorb light to render metal black--creating a material that both absorbs light
It currently takes an hour to etch a square inch of metal surface using an extremely powerful laser that reaches peak power equivalent to that of North america's entire power grid (luckily each pulse lasts only 1 femtosecond--1 quadrillionth of a second.
When a powerful laser interacts chemical and biological molecules, the process can excite vibrational modes of these molecules and produce inelastic scattering, also called Raman scattering, of light.

but POWERFUL LASER suitable for very SMALL sharks Shrinking the scale of semiconductor materials to help build powerful quantum computing systems has proved to be a real head-scratcher for scientists.
These super powerful laser pulses produced microgrooves on top of which densely populated, lumpy nanostructures were formed. The optical and wetting properties of the surfaces of the three metals were altered by these nanostructures.
