Abstract
Time-sharing optical tweezers shares a single laser beam between several trap positions. The sharing rate or trap switching frequency is an extremely important parameter in time-sharing optical tweezers especially when it performs in low frequency ranges. The effective stiffness of a novel time-sharing optical tweezers is investigated with different switching frequencies. Our experimental results show that the larger the frequency is, the stiffer the trap is in low frequency range from 5Hz to 50Hz.
