Shaping of light beams along curves in three dimensions

October 3, 2014

Researchers at the University Complutense Madrid (UCM) have recently presented a method for generating laser beams whose intensity and phase are prescribed along arbitrary 3 dimensional curves.

Using a ventus 532 1.5W laser from Laser Quantum, the beams are focussed to the diffraction limit with high intensity and controlled phase gradients that make them attractive in such applications as laser micromachining and optical trapping.
