The radial energy density profile of a laser beam that is to be injected into the kilojoule laser system must be such that diffraction effects,which may lead to self-focusing,are minimized while at the same time energy extraction is maximized. Although the two effects are interrelated they are...

Laser beam shaping systems converting Gaussian to flattop or other irradiance profiles are used in various solar cell manufacturing laser technologies to enhance their performance. Scanning over whole working field with using popular 2- and 3-axis galvo mirror scanners is very often important part of...
Researchers from Osaka University have developed a technique for improving accuracy of laser beam shaping and wavefront obtained by conventional methods with no additional cost by optimizing virtual phase grating. The results of their research were publi
The kinetic energy distribution of the protons was measured by two TPSs (TPS15 and TPS45, positioned at 15° and 45° with respect to the laser propagation direction) and a TOF detector (TOF31, positioned at 31°). The spatial proton beam profile was characterized either by an imaged ...
