This study demonstrates a method for microparticle optical trapping of silica gel using a stable Q-switched fiber laser (QFL) pulse. Gold nanoparticle (Au-NP) were fabricated as saturable absorbers on a side-polished optical fiber (SPF) to achieve stable QFL pulses of frequencies 25.81 kHz. Silica g...
