We suggest an optical tweezer setup based on an optically biaxial crystal. To control movements of opaque particles, we use shifts. The results of experimental studies are reported which are concerned with this laser tweezer setup. We demonstrate a movement of microparticles of toner using a singular-optical trap, rotation of particles due to orbital angular momentum of the field, and converging or diverging of two different traps when changing transmission plane of polariser at the input of our polarisation interferometer.

Keywords: optical tweezers, biaxial crystals, shift polarisation interferometer, singular-optical trap

Анотація. Запропоновано схему оптичного пінцета, що базується на використанні двовісних кристалів. Для керування рухом непрозорих частинок використано поляризаційний інтерферометр зсуву. Наведено результати експериментального дослідження можливостей цієї схеми пінцета. За допомогою сингулярного-оптичної пастки продемонстровано рух мікрочастинок тонера, обертання частинок, зумовлене орбітальним кутовим моментом поля та зведення двох пасток при повороті лінійного поляризатора на виході поляризаційного інтерферометра.
