If a collimated Gaussian beam is used the Top Hat beam shaping lens delivers at the working distance d=250 mm a square Top Hat beam profile with the size of 4x4 mm2. Beam diameter at beam shaper lens ...

In the St. Andrews experiment, a Gaussian beam (a light beam where the profile is described by a Gaussian mathematical formula) is generated by a VERDI V5 laser.

In this case, the use of a second order Gaussian or super-Gaussian (Gaussiann) reflectivity profile allows both maximum power extraction from the resonator, as well as a smooth far field output beam ...

It is expected that Bessel-Gaussian beams will be widely used in laser radar, and laser sensing. Advanced Search. Home; ... the BGb profiles operated at wavelength range from 1500 nm to 1630 nm ...

In a related part of 4MD at Hariot-Watt, the group has speeded-up the laser exposure process 12-fold by moving away from the natural Gaussian distribution of energy across the writing laser beam and ...

Gaussian-shaped laser-beam frequency spectrum can now be translated into a collimated flat-top beam that propagates with little change in power and intensity or loss of uniformity over large ...

The quest for a real life tractor beam continues, with a 2-micrometer-thick silicon light bender. The silicon metasurface changes a solid beam into a triple spiral one that can pick up particles ...
