Abstract

In this work, we optically trap micro-particles with higher-order frozen waves using holographic optical tweezers. Frozen waves are diffraction-resistant optical beams obtained by superposing co-propagating Bessel beams with the same frequency and order, obtaining efficient modeling of its shape. Based on this, we developed a holographic optical tweezers system for the generation of frozen waves, and with this, it was possible to create traps in a stable way for the trapping and guiding of micro-particles in the transverse plane. The experimental results show that it is possible to obtain an excellent stability condition for optical trapping using higher-order frozen waves. These results indicate that frozen waves are promising for optical trapping and guiding of particles, which may be useful in various applications such as biological research, atomic physics, and optical manipulations using structured light with orbital angular momentum.
